Photosynthesis is the process that traps the Sun's energy in food. Respiration is a process that releases energy from food.
(31) How do mitosis and meiosis differ?
Mitosis produces cells with the same number of chromosomes as the parent cell. Meiosis produces egg and sperm cells with half the number of chromosomes as the original cell.

Viruses are not cells and do not carry out life processes.
(4th Review) How are a kingdom and a phylum related?
A phylum is a main group within a kingdom.

outer body case and segmented legs
(36) virus
a microscopic particle made of hereditary material and a protein coat, which can reproduce inside a living cell
(34) How are plants grouped? How does this differ from animals?
Plants are grouped by division. Animals are grouped by phylum.
(34) What classifies an organism as a plant?
Answers vary, but may include that plants have many cells, cell walls, a true nucleus, and roots; and the cells have chlorophyll.
(34) How do mosses differ from seed plants?
Mosses are seedless and have spores.
(37) spore
A spore is a cell that can develop into an adult organism without fertilization.
(4th Review) What two kingdoms contain bacteria?
Eubacteria (or "true bacteria") and Archaebacteria (or "ancient bacteria")
(34) How are cone-bearing plants similar to flowering plants?
Cone-bearing plants are similar to flowering plants because they both reproduce with seeds.
(34) Which divisions of the plant kingdom are the most similar? Why?
Flowering plants and cone-bearing plants are most similar, because they both have seeds.
(37) metamorphosis
Metamorphosis is the changes of body form that some animals go through in their life cycle.
(34) Which divisions of the plant kingdom are the most different? Why?
Ferns and mosses are the most different, because mosses do not have special tissue for transporting water.
(37) fission
Fission is a kind of asexual reproduction in which one parent cells divides into two offspring cells.
(4th Review) What are the two types of asexual reproduction?
fission, budding
(4th Review) What kingdom includes mosses?
(31) Which parts of a plant cell are not found in an animal cell?
