Brooks Biodiversity Unit 3
Exam
,1. Plants Architecture
ANSWER Plant needs
i. collection & conversion of solar energy -> leaves
ii. positioning & support of leaves -> stems
iii. anchorage & absorption -> roots
iv. transport -> vascular system
2. Leaf Structure
, ANSWER Epidermis, Mesophyll, and Vein (Vascular Bundle)
3. Epidermis contains what?
ANSWER - Cuticle
- Guard cells with Stomata
4. Epidermis
ANSWER outermost cell layer of a plant body
cutin
(wax) excreted by epidermis
5. Cuticle
ANSWER Waxy waterproof covering of a plant. Produced
by the epidermis and has wax to resist desiccation.
6. Guard Cells
, ANSWER Responsible for opening and closing stomata. Works
together with stomata to regulate gas exchange.
Prevents movement of water ACROSS surface
7. Stomata
ANSWER Small openings on the underside of a leaf through which oxygen and carbon dioxide can move.
Mostly on lower surfaces, sometimes on upper surfaces. Found on both surfaces.
Allows for gas exchange.
8. 2 aspects of Photosynthesis
ANSWER light dependent reactions light independent
reactions
9. Mesophyll contains what?
ANSWER - Parenchyma
