| 1/2 major groups of angiosperms = Dicot ( most flowering plants, shrubs, woody trees, roses, cactus, carrots, radishes. |
|
Definition
| 2 cotyledons, branched veins. vascular bundles in rings, floral parts are in 4 or 5's, Taproot ( long and branching) present. |
|
|
Term
| 1/2 major groups of angiosperms = Monocot ( non wood plants, like bamboo, orchids, grass, rice, wheat). |
|
Definition
| one cotyledon ( inside long shit), parallel veins, complex vascular bundles, floral parts are in 3's, fibrous root system. |
|
|
Term
| Plant body is divided into roots and shoots. what do each do? |
|
Definition
Shoots : photosynthesis, gas exchange, reproduction, food/water storage
Roots: anchorage, absorb and transport water and minerals, store food. |
|
|
Term
|
Definition
| Stems, which are composed of nodes ( that the flowers and leaves stick on) and internodes ( basically regions btwn the nodes). Leaves, which are made of photosynthestic blade and petiole. Buds, which are underdeveloped shoots. Axillary buds occur at nodes and can be induced to make new branches, and widen width. Terminal buds grow in height. |
|
|
Term
|
Definition
| root hairs, are extensions of individual epidermal cells and greatly increase the surface area of the root. |
|
|
Term
|
Definition
| terminal buds that inhibit the axilliary buds, because they want to go UP more than the plant should widen. |
|
|
Term
|
Definition
| Store food ( carrots, beets) |
|
|
Term
|
Definition
| runners of strawberries, tubers of potatoes ( for food storage), rhizomes of iris plants for food storage and a sexual reproduction |
|
|
Term
|
Definition
| tendrils of cucumbers and peas used for climbing, spines of cacti used to protection |
|
|
Term
| Features of plant cells not found in animal cells |
|
Definition
| Chloroplasts, central vacuole, pits with plasmodesmata ( channels to communicate bwtn cells), cell walls made of cellulose |
|
|
Term
| 6 major types of plant cells |
|
Definition
parenchyma cells ( most are), collenchyma,
sclerenchyma,
water-conduction cells of xylem tissue, food conduction cells of phloem tissue |
|
|
Term
| parenchyma cells ( most are) |
|
Definition
| thin primary wall, food storage, photosynthesis, aerobic respiration |
|
|
Term
|
Definition
|
|
Term
|
Definition
| DEAD at maturity, lignified, rigid cell walls, support and protection. 2 types, fibres and sclereids. |
|
|
Term
| water-conduction cells of xylem tissue, |
|
Definition
| DEAD, enlongated, transport H20 and minerals, support. they include tracheids which are tapered ends with open pits. Vessel elements are wider, and shorter with ends COMPLETELY open. |
|
|
Term
| food conduction cells of phloem tissue |
|
Definition
| sieve tube members are alive, but have no nuclei, ribosomes so they rely on companion cells. the ends are sieve plates with many plasmodesmata and transport sugar and other food. |
|
|
Term
| Plants have how many tissue systems? Each is CONTINUOUS thru the plant. |
|
Definition
| 3 systems. Dermal, ground and vascular. |
|
|
Term
|
Definition
| single cell layer, with waxy cuticle and trichomes ( root hairs) guard cells and stomata. |
|
|
Term
|
Definition
| Xylem and Phleom tissue ( water and food). Transport, structure support. |
|
|
Term
|
Definition
| Various cell types, mainly parenchyma ( food storage, photosynthesis...) fils spaces btwn dermal and vascular systems.. |
|
|
Term
| In roots, the epidermis lacks a ____. |
|
Definition
| Cuticle. the inner layer of the cortex ( endodermis) acts a selective barrier, regulating the passage of stuff into the vascular tissue. |
|
|
Term
| in Stems, the epidermis has a ____. |
|
Definition
| Cuticle. Dicots have vascular bundles in a ring surrounding the cortex ( ground tissue) and monocots the vascular bundles are scattered everywhere. |
|
|
Term
| In leaves, there is a cuticle on all of the epidermis. also on all surfaces: |
|
Definition
| there are guard cells, stomata. mesophyll ( ground tissue) is on the lower half of the leaf, for gas exchange. Veins, which are vascular bundles, are throughout the leaf. |
