In plant seeds, what is the testa? What does it do?
The testa is the "seed coat" that protects the embryo and endosperm.
If a cell is haploid, what does it contain?
The cell will contain only HALF of the chromosomes needed to be that organism. The chromosomes will NOT be partnered up.
What are ovules?
They are basically the "ovaries" of plants where haploid egg cells are produced.
In plants, what is meiosis used for?
Meiosis is used for making haploid gametes (sperm and egg)
In plant embryos, what is a radicle? What does it do?
A radical is an embryonic root. It absorbs nutrients and water from the soil.
Plant Trivia! For a lot of points! How many pencils can be made from an average sized tree?
Around 170,000.
In plants, what are embryos?
An embryo is a "baby plant" found within a seed. It is a immature sporophyte. It is diploid and the result of fertilization.
Which type of plant only has one cotyledon
Monocotyledons (also known as monocots)
What are seeds?
Seeds are mature, fertilized ovules. They can be described as the dispersal and propagation units of seed plants, conifers and angiosperms.
What is the function of a cotyledon? What does it do?
A cotyledon is the part of the seed that will grow into the leaves.
Which type of plant has two cotyledons?
Dicotyledons (also known as Dicots)
Which of the following are considered to be fruits? 1) Apples 2) Tomatoes
Both apples and tomatoes are fruits? Why? They both contain seeds!
In a plant seed, what is endosperm? What does it do?
Endosperm is the food storage tissue inside a seed. An embryo gets nutrition from endosperm until it can photosynthesize for itself. Endosperm is triploid (3n),
In plant embryos, what is an epicotyl? What does it do?
A region of an embryonic stem just above the cotyledon. This part of the embryo grows very quickly and ensures the plant breaks the surface of the soil.
If a cell is diploid, what does it contain?
The cell will contain ALL of the chromosomes needed to be that particular organism. The chromosomes will be paired up.
In plants, what is a hypocotyl? What does it do?
The hypocotyl is an area below the cotyledons where a lot of cell division (mitosis) takes place. It causes rapid linear growth (length) and becomes the stem.
Plants have an alternation of generations in their life cycle. What does this mean?
Alternation of generations is a type of life cycle found in plants in which generations of individuals alternate between haploid and diploid organisms.
In plants, what is mitosis used for?
Mitosis is cell division. It is used for growth and development.
