Term
xylem
Definition
the tubes in plant stems that transport water and minerals in vascular plants
Term
phloem
Definition
the tubes in plant stems that transport food in the vascular plants
Term
chlorophyll
Definition
a pigment, or coloring matter, that helps plants use light energy to produce sugars
Term
nonvascular
Definition
a term for plants that do not have xylem and phloem. they can move water, minerals and food only from one cell to the next. This is why they are small.
Term
vascular
Definition
term that describes a plant with xylem and phloem. They are able to grow larger than nonvascular plants.
Term
spore
Definition
a single reproductive cell that grows into a new plant in nonvascular plants
Term
gymnosperm
Definition
plant with unprotected seeds; conifer or cone-bearing plant
Term
pollen
Definition
flower structures that contain the male reproductive cells
Term
angiosperm
Definition
a flowering plant
Term
grain
Definition
the seed of certain plants
Term
fiber
Definition
any material that can be separated into threads
Term
Name the two type of tubes that transport materials in plant stems.
Definition
xylem and phloem
Term
What are called the "food factories" of plants?
Definition
leaves
Term
Why are the parts of some plants very different from those of other plants?
Definition
Plants are able to live in different environments because their roots, stems and leaves are adapted to the environments in which they live.
Term
What are taproots?
Definition
it is a single, thick root that grows straight down. They can reach water that is deep in the ground.
Term
fibrous roots
Definition
roots that form a thick and tangled mat just under the surface of the soil. They help prevent soil erosion because they anchor the soil as well as the plant.
Term
Why do leaves change color in the fall?
Definition
The days grow shorter and so there is less chlorophyll to give the leaves their green color. It is not due to frost.
Term
What are the two major groups of plants and how are they different?
Definition
nonvascular - does not have xylem or phloem, doesn't flower, is smaller, and they reproduce with spores
vascular - has xylem and phloem, grow larger, many flower, reproduce with male and female cells
Term
How do simple vascular plants reproduce?
Definition
They produce male and female reproductive cells, the united cell, called a zygote, divides and grows into a separate spore-producing plant.
Term
What are the two types of see-producing vascular plants and what is the difference?
Definition
gymnosperms - with unprotected seeds
angiosperms - produce seeds protected by some type of fruit
Term
What type of plant accounts for nearly all the food that people eat?
Definition
flowering vascular plant
Term
How are gymnosperms pollinated?
Definition
Wind carries pollen from the male cones to the female cones.
Term
How are angiosperms pollinated?
Definition
they are pollinated by the wind, insects and other small animals
Term
Which are important sources of wood, fiber and medicine? Angiosperms or gymnosperms?
Definition
Angiosperms
Term
Name some examples of the fruits produced by angiosperm to protect their seeds.
Definition
Apples, oranges, tomatoes, peanuts, and acorns
Term
How does a fruit protect the seeds inside?
Definition
1. it usually keeps birds and other animals from getting at them, even if they eat the outer part of the fruit
2. serves as a covering that protects the seed from cold weather
3. rottin fruit provides extra food for a new plant when it begins to grow
Term
Describe the life cycle of the flowering plant (angiosperm).
Definition
It starts as an embryo inside a seed. Then the embryo grows into a seedling. Then the seedling grows and matures and flowers. Then each flower produces seeds inside a fruit like covering.
Term
How are the life cycle of a flowering plant similar to that of an animal?
Definition
They both have an embryo stage. They both have male and female reproductive cells. They both look more like their parents the more they grow and mature. They both go through several divverant stages in their life cycles.
Term
How do conifers produce seeds?
Definition
Conifers produce both male and female cones on the same tree. Male cones produce pollen which is carried to the female cones by the wind. The male and female reproductive cells unite into a zygote. The zygotes then divide and grow into seeds.
Term
How do ferns reproduce?
Definition
Ferns produce both male and female reproductive cells. The united cell, called the zygote, then divides and grows into a separate spore-producing plant.
Term
Name the plant parts that people eat.
Definition
Leaves, seeds, fruit, stems, flowers, and roots
Term
What did people do before aspirin was invented?
Definition
They chewed on the bark of the willow tree.
Term
Name some products made from trees.
Definition
paper, furniture, homes, musical instruments
Term
What percentage of the medicines we use come from plants?
Definition
40%
Term
The aloe plant is used to make what products.
Definition
skin creams, makeup, shampoos, soaps, and sunscreen
Term
What forms the largest part of the food pyramid?
Definition
Grains
Term
What forms the second largest part of the food pyramid?
Definition
vegetables and fruits
Term
What are the two groups of seed-producing plants?
Definition
gymnosperms - unprotected seeds
angiosperms - protected seeds
Term
Why are most leaves thin and flat?
Definition
It helps them to make food.
Term
Why are nonvascular plants limited in size?
Definition
Because they have to pass water and minerals from one cell to thenext.
Term
Why are bright, large, colorful leaves beneficial to the plant?
Definition
They attracct insects and birds that spread pollen.
Term
In order to eat a more healthful diet, should you eat foods closer to the top of the food pyramid or closer to the bottom?
Definition
Closer to the bottom because grains make up the bottom, or largest part and directly above that are the fruits and vegetables.
Term
In what way are fruits better than cones for carrying seeds?
Definition
Fruits provide protection for the seeds and give them a better chance of survival. If they are rotting, they also provide food for the growing seed.
Term
Coud a plant live if all its leaves were cut off?
Definition
No because leaves are responsible for making the food.
Term
What are the 3 main parts of a plant and what is their purpose?
Definition
roots - anchor a plant and take in minerals and water from the soil
stem - supports a plant and moves materials between its parts
leaves - make the plant's food
Term
stomata
Definition
tiny holes in a leaf where carbondioxide enters and oxygen exits
Term
stem
Definition
a plant part that holds the plant up and carries food and water to other plant parts
Term
root hairs
Definition
tiny parts of roots that take in water and minerals from the soil
Term
chloroplasts
Definition
the parts in leaf cells where the food-making process takes place
Term
prop roots
Definition
roots that begin above ground so they can keep trees growing in loose, wet soil from being blown over by the wind
