Plant cell
Why are plants important?
air, photosynthesis, etc
What is a shoot?
Part above the ground (stem+leaves)
Describe the 3 types of ground tissue
-parenchyma: synthesizes and stores food
sclerenchyma: rigid support of plant
collenchyma: plant support
Mention one example of a modified stem
onion, potato, etc
what is plasmodesmata?
connection between 2 cells
Describe 2 functions of leaves
photosynthesis, reduce water loss
Describe the location and function of meristem
-found in actively growing regions(apical or axilary buds)
- growth
Explain 2 leaves adaptations
tendrils, spine leaves, storage leaves, reproductive leaves
Mention the differences between plant cell and animal cell
-plant cells have a cell wall and animal cells don't
-plant cells have chloroplasts and animal cells don't
-plant cells have vacoules
Describe 3 functions of stems
Physical support, growth, lateral growth, storage
Describe the different cell types found in a plant leaf.
epidermis, guard cells, mesophyll, xylem, phloem, bundle sheath cell
Mention 2 root modifications and their environment
aerial roots
storage roots
buttress roots
What makes up the plant cell wall?
cellulose, hemi-cellulose, lignin, lamella
Describe 4 functions of the roots
-anchor the root
-absorbs water and nutrients
-storage of nutrients
-growth
Compare and contrast xylem and phloem?
-xylem moves in one direction, phloem moves in 2
-Xylem: water+minerals vs phloem: water+food
-Xylem: no end walls vs phloen: cell walls with holes
Mention one plant adaptation and what drove that adaptation
example
Give 2 examples of macronutrients and 2 of micronutrients that are required by plants.
Nitrogen, Phosphorus, potassium
Iron, Manganese, Boron, Zinc, Chlorine, Sodium, Cobalt
How does lateral growth occur in trees?
lateral meristem. Talk about wood rings and cambium
Explain/draw the differerent types of tissue as found in a monocot root
drawing
Describe 4 adaptations that xerophytic plants have to help them survive
-increase water uptake (deep/spread roots)
-increase water uptake (high salt content)
-waxy cuticle
-reduced stomata
