What are the parts of most plants?
roots, stems, leaves
What is photosynthesis?
process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen
What are vascular plants?
plants with a tubelike system of vessels
What is "pioneer species?"
name given to the first plants that grow in new environments
What is the cuticle?
waxy layer on stems and leaves that repels water
What is cellulose?
composes the cell wall of plants
What is "to make food for the plant"?
the major function of leaves
What are phloem?
tissue that moves food from leaves to other plant parts
What are rhizoids?
Moss plants are held in place by threads made up of only a few long cells called this.
What are stomata?
small pores in the leaf surface
What are rhizoids?
What is the sun's energy?
without this a plant could get water and nutrients from the soil, but not be able to create food for the plant through photosynthesis
What is xylem?
tissue made up of tubular vessels that transport water and minerals up from the roots throughout the plant
What is "the first plants to grow in a new environment?"
pioneer species are these
What are guard cells?
in a plant leaf, cells that surround the stomata to open and close them
What is "absorbing water and minerals, anchoring the plant, and storing food'?
What are small openings in the epidermis that allow carbon dioxide, water, and oxygen to enter and exit a leaf
stomata
What is cambium?
tissue that produces new xylem and phloem cells
What are seedless nonvascular plants?
horsetails and mosses fall into these 2 categories
What are "ancient green algae?"
scientists hypothesize plants evolved directly from this
What are stems?
This part of the plant stores food for the plant, supports the aboveground parts of the plant, and allows movement of materials between leaves and roots.
What is oxygen?
The waste product created by the plant after the completion of photosynthesis
What are "plants without vessels such as mosses and hornworts that absorb water directly from the damp ground"?
nonvascular plants
What is the part of the plant that contains chloroplasts, where food is made?
palisade layer
What is the palisade layer?
these cells have chloroplasts filled with chlorophyll
