Stomata allow gases to move into or out of a leaf. What structure allows gases to move easily within the leaf itself?
Spongy Layer
What are the 2 main types of roots plants can have and give examples of each?
Taproot - carrot Fiborous - grass
How do cell walls and turgor pressure help support the weight of a plant?
The céllulose in the cell walls make them rigid. Turgor pressure causes the cells to swell and support the plant.
Label the diagram
1 = Cuticle 3 = Palisade layer 4 = Chloroplast 5 = Vein 6 = Spongy layer 7 = Stoma
What are the 3 main types of plants and give examples of each.
1. Nonvascular - moss; 2. Seedless vascular - ferns 3. Seeded - rose
What are the 2 main types of seed plants and give an examples of each?
Angiosperm - watermelon Gymnosperm - Pine tree
Why do trees for annual rings?
Because xylem grows differently at different times of year.
What are the different components of tree bark?
Cork and a ring of phloem
How can a cornstalk remain standing long after it has dried out and lost turgor pressure?
Cornstalks are supported by the fibers around the vascular bundles of their stems.
What is the difference between a dicot and monocot?
Dicot - Their vascular bundles are in a ring around the outer part of the stem. Monocot - Their vascular bundles are evenly distributed throughout the stem.
How are plants classified?
If they have vascular tissue and if they reproduce with seeds.
What are mosses unable to grow very tall?
Mosses are nonvascular and their water is Transported by diffusion and can only travel short distances.
Define turgor pressure.
Pressure caused by the presence of water inside a plant cell's central vacuole that helps support a plant stand up.
A rose bush produces red flowers. What kind of plant is it and how do you know?
