Cell Cycle and Reproduction

Cell Cycle

100

the longest phase of the cell cycle

interphase

200

The cell cycle is divided into two phases; interphase and the ____________ phase. Must be able to spell it correctly in your verbal answer.

Mitotic

300

Prophase, Metaphase, Anaphase, and Telophase are known as _____________

mitosis

400

The first phase in mitosis is ________________. In this phase the nuclear envelope is broken down and rearranged to make the spindle apparatus.

prophase

500

This is where the new daughter cells spilt into two new cells after mitosis

cytokenesis

The Cell

100

This is a _________ membrane which allows some material to move in and some material to move out. (adjective)

semipermeable

200

Chromosomes are located within the ___________.

nucleus

300

The organelles that we studied from the last test are found within this main part of all cells.

cytoplasm

400

DNA is coiled on the ________________.

chromosomes

500

Name the three main parts of all cells

Cell membrane, cytoplasm, nucleus

Phases

100

1) copied DNA condenses into chromosomes 2) the nucleolus disappears, and the nuclear membrane breaks down 3) spindle fibers begin to form

prophase

200

1) chromosomes line up in single file at the MIDDLE of the cell

Metaphase

300

1) Sister chromatids separate 2) spindle fibers begin to shorten, pulling chromatids toward opposite sides of the cell 3) the cell begins to lengthen

anaphase

400

1) a nuclear membrane forms around the chromatin 2) chromosomes begin to unwind 3) spindle fibers begin to break down 4) two identical nuclei form LAST PHASE of mitosis

telophase

500

Name the four phases of mitosis in order - the clock

prophase, metaphase, anaphase, telophase

POT LUCK

100

Diffusion through a membrane is known as ______.

Osmosis

200

How many PAIRS of chromosomes are in each human body cell except for gametes?

23

300

Yeast cells produce carbon dioxide and _______ as wastes during fermentation.

alcohol.

400

What does ANAEROBIC mean?

without oxygen

500

Many-celled organisms are called ____________

multicellular

Cells and Energy

100

this is a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP

cellular respiration

200

Cellular respiration occurs in the cytoplasm and within this organelle

mitochondria

300

This is the reaction that eukaryotic and prokaryotic cells can use to obtain energy from food when oxygen is LOW

fermentation

400

This is a series of chemical reaction that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and gives off oxygen

photosynthesis

500

Photosynthesis takes place in what part of the plant?

The LEAF
