How do insects help a plant reproduce?
Insects help the pollen tubes grow from the style of the plant.
Insects help move pollen from the anthers to the stigma.
Insects help the stigma produce pollen to be moved to the anthers.
Insects feed on plant nectar and use it to make honey.
What must happen before mitosis to ensure that each new cell will be an exact copy of the parent cell?
Telophase
Mitochondria must create ATP
Chromosomes are copied.
Cytokinesis
In self pollination, pollen that is produced in the (a) of the plant is transferred to the (b) of the same plant. (c) grow from the pollen grain and carry (d) to the (e)
In (a) the pollen is transferred from the (b) to the (c) of the same plant.
During (a) the pollen is transferred from the (b) of one plant to the (c) of another plant.
In some plants, the pistil doesn't form until a few days after the stamens do. How might this keep a plant from self pollinating?
Without the pistil there is no anther to produce pollen.
Without the pistil there is no nectar for insects to eat.
Without the pistil there is no stigma to receive the pollen.
Without the pistil there are no petals to attract insects.
When does the cell cycle begin?
When the cell divides and makes new cells.
When the new cells are formed.
When the cell uses energy.
When the cell takes in oxygen.
A small leaf that protects the flower before it blooms.
Petal
Sepal
Flower
Cell Wall
When does the cell cycle end?
When the cell divides to make new cells.
When the new cells are formed.
When the cell uses energy
When the cell takes in oxygen
Programmed cell death, the process that causes cells to self destruct.
Mitosis
Meiosis
Apoptosis
Phagocytosis
What makes cancer cells different than normal cells?
They are no longer human cells
They ignore signals for self destruction and continue to divide.
They do not have a nucleus.
They are infected with bacterial DNA.

Eukaryotic
Match the following
The female structure of the flower
Pistil
The male structure of the flower
Stamen
The sticky part of the female portion of the flower where the pollen germinates.
Stigma
The part of the male portion of the flower that produces and contains the pollen.
Anther
Match the following
Typically yellow, microscopic grains that are discharged from the anthers. Each grain contains a male gamete.
Pollen
The female gamete or sex cell.
Egg
The male gamete or sex cell.
Sperm
Naturally occurring genetic differences among organisms of the same species.
Genetic Variation
Match the following
A cell without a nucleus.
Prokaryote
A cell with a nucleus.
Eukaryote
The second stage of the cell cycle in eukaryotes that forms 2 new nuclei each with the same number and arrangement of chromosomes.
Mitosis
The 3rd stage of the cell cycle when the cell splits into two cells that are identical to each other and to the parent cell.
Cytokinesis
The region where chromatids are held together.
Centromere
Chromosomes that have the same sequence of genes and structure.
Chromatids
Daughter Cells
Homologous Chromosomes
Twin Chromosomes
The result of mitosis, the two identical copies of the original parent cell.
Homologous chromosomes
Daughter Cells
Sister Chromatids
G2 Cells
Name and describe the phase of the cell cycle shown in the picture:
Interphase- Mitosis begins. The chromatids condense to form long strands or thick rods. Often shown as an “X” shape.
Interphase - Before mitosis begins, chromosomes are copied. Each chromosome is made of 2 chromatids.
Anaphase -The chromatids separate and move apart to opposite sides of the cell.
Metaphase - The nuclear membrane is fully dissolved. Chromosome pairs line up along the equator (middle) of the cell.
Name and describe the phase of the cell cycle shown in the picture:
Prophase - Mitosis begins. The chromatids condense to form long strands or thick rods. Often shown as an “X” shape.
Anaphase -The chromatids separate and move apart to opposite sides of the cell.
Anaphase - The nuclear membrane is fully dissolved. Chromosome pairs line up along the equator (middle) of the cell.
Telophase - A nuclear membrane forms around each set of new chromosomes.The chromosomes unwind. Mitosis is complete.

Telophase - The final stage in the cell cycle. In cells without a cell wall the cells will pinch into 2 new daughter cells.
In cells with a cell wall, a cell plate forms and separates the new cells.
