Cell Processes Study Guide – Photosynthesis, Cellular Respiration, The Cell Cycle, and
Asexual/ Sexual Reproduction
Photosynthesis
1. During photosynthesis, the ______________________________ captures the energy in
sunlight to produce food for the plant.
2. The starting materials used during photosynthesis are carbon dioxide and _______________.
3. The products of photosynthesis are oxygen and ___________________________.
4. The chemical equation below describes the process called ___________________________.
5. Plants make sugar to use for energy through a process called ________________________.
6. The chloroplast needs the gas ___________________________ to make sugar.
Cellular Respiration
7. Most complex organisms get their energy through _____________________________.
8. The starting materials used during cellular respiration are ___________________________
and sugar.
9. The products of cellular respiration are _____________________ and water.
10.The mitochondria need _______________________________ gas to break down sugar and
release energy.
11.Cells withdraw energy from the food you eat through the process of
_______________________________.
The Cell Cycle
12._____________________________ is the process that produces two identical daughter cells.
13._____________________________ cells end up with the same number of chromosomes as
the parent cell after mitosis.
14.Before a cell can divide, the DNA in the nucleus must be _________________________ or
copied.
15.During __________________________ the cell grows to its mature size and makes a copy
of its DNA.
16.The process in which DNA makes a copy of itself is called _________________________.
17.During the ____________________________, DNA is replicated, chromosomes line up and
separate, and the cell pinches in two.
18.Cells need to produce new cells in order to replace
________________________ cells.
19.The cellular process shown to the right is called
_____________________.
20.Once the cell cycle is complete, there will be ______
daughter cells.
DNA
21.Chromosomes, genes, and DNA are all located in the _____________________.
22.Chromosomes are made of ______________________.
23.DNA is necessary in a cell because it is the _____________________________.
