JT's vascular plants

5th grade science

Waht are the 3 main parts of vascular plants? roots, stems and leaves
What is the purpose of the root system? holds the plant in place and stores food
The stem and leaves form what system of the plant? stem and leaves form the shoot system
What is the purpose of the shoot system? is to support the plant,to transport materials and to produce food.
What are the 2 types of vascular plants? seedless and seed
How do seedless plants develop? from spores
What is a spore? a single cel tlhat can develop into a new plant that is exactly like the plant that produced it.
What is a seed? contains an undeveloped plant, stored food and a protective covering.
How do seed plants make more of themselves? when male and female cell are joined.
How do seedless plants make more of themselves? reproduce through spores.
What is an angiosperm? a seed plant that produces flowers.
Give 3 examples of an angiosperm. Fruits, vegetables, and grains
What is a gymnosperm? a seed plant that doesn't produce flowers.
Give an example of a gymnosperm. Evergreen
What are flowers? The reproductive organs of angiosperms
What is the make part of a flower called? stamen
what does the stamen produce? pollen grains
What is female part of the flower called? pistil
How and why do flowers attract animals? Flowers have bright colors, scents and nectar to attract animals (insects, birds, small mammals)
What is it called when the pollen and egg cell join to form a seed? Fertilization
What is the purpose of fruit? protects the seeds inside the flower
Name 3 ways seeds are dispersed? animal fur and droppings, through special winged structures seeds might have
What is the job of a root in transporting things for the plant? store food anchor the plant and carry water anf minerals up the stem to the leaves.
What is the job of a stem? develop buds and shoots and usually grows above the ground. It houses the transport system.
What is the job of a leaf? a leaf releases gases into the air and produces sugar.
What connects the leaf to the stem or branch? the petiole connects the leaf to the stem or branch.
What do leaves use to produce sugar? water and carbon dioxide
what is the job of the xylem? to move water and minerals up from the roots.
what is the job of the phloem? to move sugar produced in the plant's leaves to the other parts
What is the name of the place where xylem and phloem cells are produced? cambium
what is the function of bark> protective layer around the tree.
what do lighter rings tell you? formed during spring whe good conditions for growht occur.
What do darker rings tell you? grow during autumn when there is little water.
what do larger rings tell you? there was alot of rainfall that year.
Describe a taproot one large root within a few branching hairy roots
3 examples of taproots are dandelions, beets, carrots
where to taproots tend to grow deep into the soil
describe fibrous roots thing branching roots
example of a fibrous root grass
describe prop roots grow like fingers out of the bottom of a stem
example of a prop root corn
describe aerial roots never touch the ground
example of an aerial root ive and orchids
What is photosynthesis? food making process of plants using energy from sun and water, absorbed by roots and carbon dioxide from the air to make food
what is needed for photosynthesis to occur sun, carbon dioxide (co2) and water (h20)
what does carbon dioxide enter the plant? through the stomata
what happens to the stomata when there is little water? guard cells close and preserve water
what happens to the stomata when there is too much water? guard cells open
where does photosynthesis take place in the choloroplasts
what is the name of the chemical that absorbs light energy? chlorophyl
photosynthesis creates sugar for teh plant What is the sugar used for? for food
what is teh waste plants make? oxygen
what is the chemical equation for photosynthesis? 6CO2 + 6H2O + energy > C6H12O6 + 6o2
what is the purpose of photosynthesis and Respiration cycle? provide energy to plants and animals
What is the name of the sugar plants produce during photosynthesis? carbohydrate
what is a carbohydrate made from? carbon, hydrogen, and oxygen
Why do animals also depend on photosynthesis? because of the food chain
what do you call it when animals breathe in oxygen? cellular respiration
when would an animal of plant use oxygen? when the cell needs energy.
Why are Photosynthesis and respiration are opposites? cellular respiration is co2 + h2o, photosynthesis uses co2 and h2o to produce sugars
Where does cellular respiration occur in cells? mitochondria of a cell
What is the energy for? help plant and animal cells grow and repair themselves
what do mitochondria use oxygen for? breaks down stored carbohydrates to release energy.
What is the released energy in the mitochondria called? ATP is the energy released from mitochondria
