What is the function of the roots?
Roots have two main functions: 1. They anchor the plant in the ground. 2. They suck up minerals and water from the ground. (Most water enters a plant through the roots)
100
These are the male parts of the plant.
What are the stamen?
100
Photo means _______.
What is light.
100
A baby plant is called an _______.
What is an embryo?
100
In ________ reproduction, there is only ______ parent plant, therefore the offspring and the parent plant have ____________ DNA.
What is one and same.
200
A leaf could best be classified as a(n): a. organ b. tissue c. organ system
What is an organ?
200
This is the female part of the plant.
What is the pistil?
200
Plants need _______, _______, and _______ to complete photosynthesis.
What is water, carbon dioxide, and energy from sunlight?
200
Embryos are protected by a _____________.
What is a seed coat?
200
When two plants produce an offspring by pollination, the offspring will most likely a. not look like either parent plant b. look like one parent plant, but not the other c. have characteristics from both parent plants.
What is c. have characteristics from both parent plants.
300
The tips of the stamen are called _______ and they are covered in _______.
What is anthers and pollen?
300
_______ and _______ are the two types of vessel tissues in plants.
What are xylem and phloem?
300
The products of photosynthesis are _______ and _______.
What are oxygen and sugar.
300
Identify two types of asexual reproduction and explain how each method works.
A plant may use spores to reporduce. Spores are tiny plant cells from which new plants can grow. Plants can also reproduce by budding and growing new plants from their roots and on long stems called runners.
300
_______ are ways that plants change their direction of growth in response to the environment.
What are tropisms?
400
This part of the leaf protects it from the outside.
What is the epidermis?
400
What is the function of phloem?
Phloem is vessel tissue that carries sugars produced in the leaves during photosynthesis to the rest of the plant.
400
Plants combine sugars to make _______ in order to store them for a long time.
What is starch?
400
Explain the process of pollination.
In order for pollination to occur, pollen needs to get from the tips of the stamen, or anthers, to the pistil. Pollen tubes grow down from the pistil to the egg cells. Sperm cells from the pollen move down the tubes. When the sperm cells meet the egg cells, fertilization mixex the DNA of the two. Then, over time, the fertilized egge cell will grow, divide many times, and change into a seed.
400
List and explain the three types of tropisms.
1. Phototropism is a plant's reaction to a source of light. 2. Gravitropism is the growth of a plant or plant part because of the pull of gravity. 3. Thigmatropism is a plant's growth in response to touching an object.
500
What is the purpose of the stomata?
Stomata are tiny openings on the underside of leaves. They allow carbon dioxide into the leaf and they allow oxygen to leave the leaf.
500
What is the function of the xylem?
Xylem is vessel tissue that carries water from the roots to the rest of the plant.
500
Explain why plants would have more sugar in the daytime.
Sugar is made in the chloroplast during a process called photosynthesis. To make sugar, a chloroplast needs carbon dioxide, water, and energy from the Sun. There is no sunlight during the nighttime; therefore, the chloroplast cannot produce sugar at night. At night, the plant uses the stored sugar.
500
Compare and contrast plant seeds and spores.
Spores do not have a multicellular embryo like seeds. Spores are not made by fertilization, but seeds are. Spores and seeds both have stored food. Some spores and seeds have protective coverings.
