What is a Plant - Chapter 8, Lesson 1
the green pigment that is found in chloroplasts in the majority of plants
What is chlorophyll in a plant?
thin root-like structures that anchor and absorb water & nutrients for the moss
What are rhizoids?
helps anchor the plant into the soil and absorb material, including storing material
What do roots do?
sporophyte and gametophyte
What are the two stages in a plant's life cycle?
by moving
How animals reponsd the stimuli?
organisms that live by making their own food
What are autotrophs?
xylem and phloem
What are the two types of vascular tissue?
protects the root itself from injury and damage while it grows out of the soil
What is the root cap?
annuals, biennials, and perennials
a plant's growth response toward/away from the stimulus
What is tropism?
the food-making process that occurs in plants, taking energy from the sun and turning it into nutrients for the plant
What is photosynthesis?
xylem
Which vascular tissue are considered "dead"?
sepals, petals, stamens, pisitils
What are the four main structures of a flower?
What does a plant's sexual reproduction system involve?
touch, gravity, or light
What are the three important stimuli that trigger growth in plants?
they must be able to retain and obtain water, support their own bodies and structures, reproduce, and transport matierals
What do plants need to survive on land?
they all have vascular tissue and do not produce seeds
What two characteristics do ferns, clubmosses, and horsetails have in common/share?
the process by which water evaporates from a plant's leaves
What is transpiration?
sexual and asexual reproduction
What does the amount of darkness determine for flowering in many plants?
water in the environment
What do most plants need to reproduce?
pollen and seeds
What do plants use to reproduce?
carries substances between the plant's roots & leaves. This also provides support for the plant, holds it up, and exports food
What does a stem do?
the scattering of seeds in an enviroment
What is seed dispersal?
clean water, protecting the soil and dirt in the environment, and providing medicine, paper, and clothing for us
What are some habitats that plants provide? (for us and other organisms.)
