Plant Structures
Label the structures of this plant diagram.
Ms. Schake will decide if answers are correct.
Which of the following is NOT a function of the roots? (Could be more than one correct answer)
a. Anchors the plant in the ground
b. Produces seeds
c. Absorbs sunlight
d. Absorbs nutrients
b. and c.
What does the embryo of a seed need in order to "wake up"?
Water
What are the four main stages of all animals' life cycles?
Birth, Growth, Adulthood, Death
What structure grows first after the seed is germinated? Why?
Roots grow first because they can start to absorb water and nutrients from the soil so the rest of the plant can grow.
What are two functions of the stem?
Hold the plant straight up/give it structure
Transport water and nutrients throughout the plant
When we add water to a seed and it starts growing, we say that the seed has _________.
List 2 ways the frog and butterfly life cycles are similar.
They both start as an egg.
Neither one looks like its parents when it is born. They both go through metamorphosis.
What structure gives the seedling food before the leaves grow?
Cotyldedons
What is the function of the flowers of a plant?
They grow the fruit and seeds to help with reproduction of the plant.
Why do plants need sunlight to grow?
Sunlight gives the plants energy to do photosynthesis/help them grow.
List 2 ways the frog and dog life cycles are different.
1. Frog starts as an egg when born, but dog is born alive from its mother.
2. Frog does not look like its parents when born, but dog does.
What structure grew right before the bean pods with the seeds in them appeared?
Flowers
The embryo is the baby plant. One end of the embryo grows into the ______, and the other end of the embryo grows into the ______.
Stem, roots
Students planted bean seeds in small containers with soil and water. They stored them in their desks to observe their growth. After two weeks, they noticed their plants had sprouted, but the leaves were very small and yellow. What advice could you give them?
Move their plants near a window so that the leaves can absorb more sunlight.
What stage of the plant life cycle comes after the seedling when the roots, stem, and leaves have grown?
Flowers begin to grow.
What structure does photosynthesis happen in? What ingredients does this structure absorb for this process to happen?
Leaves; They absorb air and sunlight.
Why do you think photosynthesis does NOT happen in the stem of the plant?
The stem does not face the sun to absorb enough sunlight.
One of these groups of plants was grown with nutrients added and the other was grown without nutrients. Which one is which? Give two pieces of evidence for why you think that.
Left: grown with nutrients
Right: grown without nutrients
The left has more leaves, the leaves are bigger, and the leaves are more green.
Put the pictures in order of their life cycle using the numbers 1 (start) - 7 (end).
