Definition
| "shoot apex", where the new leaves come from |
|
|
Term
|
Definition
| layer of thickened cells, protect radicle as it digs down to soil |
|
|
Term
|
Definition
| "seed leaves", "cotyledon", leaf like structure that absorbs nutrients from the endosperm (first leaf seen) |
|
|
Term
|
Definition
| protects new stem as emerges from soil |
|
|
Term
| four parts of a dicot seed? |
|
Definition
| plummule, suspensor, hypocotyl, epicotyl |
|
|
Term
|
Definition
| same as shoot apex in monocot, where new leaves come from |
|
|
Term
|
Definition
| first group of cells that emerge from seed (become the radicle) |
|
|
Term
|
Definition
| region of stem below cotyledon |
|
|
Term
|
Definition
| region of stem above cotyledon |
|
|
Term
|
Definition
| a period of suspended development until the correct conditions for growth are met |
|
|
Term
| factors for seeds to germinate |
|
Definition
| water (most important), light, scarring seed coat, extensive cold, extensive heat |
|
|
Term
| gibberellin and its function |
|
Definition
| plant hormone, triggers digestive enzymes in seed to nutrient is more easily absorbed |
|
|
Term
| four types of plant tissues |
|
Definition
| fundamental tissue (-enchymas), epidermis, transport tissue (xylem/phloem), meristem |
|
|
Term
| various zones of an early root (from bottom to top) |
|
Definition
| root cap, zone of division, zone of elongation, zone of maturation |
|
|
Term
|
Definition
| thick, tough layer of cells, protects root from soil abrasion |
|
|
Term
|
Definition
| region in root where there is rapid mitosis |
|
|
Term
|
Definition
| region where cells lengthen and grow larger |
|
|
Term
|
Definition
| cells specialize to develop normal cell tissues |
|
|
Term
|
Definition
| undeveloped, unspecialized embryonic tissue |
|
|
Term
|
Definition
| first tissue in plant, eventually develops into everything else |
|
|
Term
|
Definition
| the pattern of growth in a plant that gives priority to plant growing taller, given that apex is healthy and undamaged; makes plants 'bushy' |
|
|
Term
| example of apical dominance |
|
Definition
| cutting the top off of a plant, damages apex, therefore plant stops vertical growth and grows horizontally |
|
|
Term
|
Definition
| the mark on the stem where the previous season's leaves used to be |
|
|
Term
|
Definition
| a small bunch of tissue that forms on a stem opposite the leaf scar, gives rise to next year's leaves |
|
|
Term
|
Definition
| "leaf fall", occurs twice during the year, vasc. tissue gets blocked, so no nutrients can travel, so leaf dies and falls off |
|
|
Term
| two times when abcission occurs |
|
Definition
1. end of growing season
2. prolonged drought |
|
|
Term
|
Definition
| hormone that causes plant cells to grow longer in the absense of light or in diminished light; plant grows toward a light source |
|
|
Term
| do monocots demonstrate significant secondary growth? |
|
Definition
|
|
Term
| four types of fundamental cells |
|
Definition
| parenchyma, collenchyma, sclerenchyma, chlorenchyma |
|
|
Term
|
Definition
| large, round or irregular, unspecialized, many vacuoles, used for storage |
|
|
Term
|
Definition
| round or angular, short cylinders, somewhat thickened cell walls in corners, light duty support |
|
|
Term
|
Definition
| long, straw-like cylinders, very thick cell walls all around, die when mature, heavy duty stupport |
|
|
Term
|
Definition
| rectangular cells loaded w/choloplast, photosynthesis |
|
|
Term
| two types of transport tissue |
|
Definition
|
|
Term
|
Definition
| transport water/minerals up stem |
|
|
Term
|
Definition
|
|
Term
|
Definition
| advanced, larger, long column |
|
|
Term
|
Definition
| long straw, smaller in diameter, angular on both sides |
|
|
Term
|
Definition
| transport organic nutrients down stem |
|
|
Term
| two types of phloem cells |
|
Definition
| sieve tubes, companion cells |
|
|
Term
|
Definition
|
|
Term
|
Definition
| small round cell, almost all nucleus |
|
|
Term
|
Definition
| flat, plate-like, interlocking cells; covers outsides of leaves, stems, and roots |
|
|
Term
|
Definition
| sometimes present; wazy layer, seals off epidermis, protects from water loss |
|
|
Term
|
Definition
| come in pairs, control stomata, regulate water loss/gas exchange |
|
|
Term
|
Definition
| holes in cuticle that allow for gas exchange |
|
|
Term
|
Definition
| "root hairs", extensions of cell membrane/cell wall, increase surface area to improve plant absorbtion |
