PLANT ANATOMY
What is the purpose of petals?
Petals' Bright color attracts pollinators.
What is Germination?
Germination is the beginning of plant growth when roots begin to grow.
What is Tropism?
How plants respond to their environment, by growing/moving stems, roots, or leaves towards or away from a stimulus.
Night=
Day=
Cell Respiration
Photosynthesis
What is the purpose of a stem?
A stem supports the plant, holds up the leaves, and stores the food.
What is the difference between seeds and spores?
Seeds are bigger than Spores and Flowering and cone bearing plants produces seeds and Flowerless plants (like mosses and ferns) produces spores
What is Dormancy?
A plant delays germination until the conditions are right.
What is Hydrotropism?
A plant Grows in response to water (their roots)
Positive Reaction=towards water Negative Reaction=away from water
Dormant happens when....
Cold (winter/fall)
What is the difference between nonvascular and vascular plants?
Vascular plants are big and tall with roots leaves and stems. While nonVascular plants are small and short and do not have any true roots leaves or stems.
What is the Xylem and is it in a Vascular or nonvascular plant?
A Xylem is in a vascular plant, it brings water up from the roots (natures straws)
What is plant development?
The process of a seed growing into a mature plant.
What is Phototropism?
A plant grows in response to light.
Positive Reaction=towards light Negative Reaction=away from light
What is Photosynthesis?
Photosynthesis is the process of making sugar (or glucose) in the leaves of a plant.
What is a Phloem and is it in a Vascular or nonvascular plant?
A Phloem is in a Vascular plant, A Phloem brings food down from the leaves (natures elevators)
What is the male part of a plant called?
A stamen. A stamen consists of the anther and the filament.
What part of a plant makes Pollen?
The Anther (it is apart of the stamen)
What is Gravitropism or Geotropism?
A plant grows or moves in response to gravity.
Positive Response=with gravity, roots grow down Negative response=against gravity stems grow up
What is a guard cell?
A cell that controls when air an get in or out of a leaf.
What is the female part of a plant called?
A pistil. A pistil consists of the stigh the style and the ovary.
What is a Stomata?
A stomata is a pore on a leaf that takes in carbon dioxide from the air.
What part of a plant receives pollen?
The sign (it is part of the Pistil)
What is Thigmotropism?
A plant grows in response to touch.
Positive Reaction=towards object it touched Negative Reaction=away from plant it touched
What is Respiration?
Respiration is the process that occurs in the cells of an organism that allows it to move and grow.
What is a Sepals?
A green leaf object that protects the bud of a flower until it opens.
