Bio.3e Cell Specialization

These two cell types come from the same maple tree. In what way are they the MOST similar?

• Both of them collect sunlight for photosynthesis

• Both of them have specialized structures to absorb water from the soil

• They have the same DNA code

• Both types have cell walls, nuclei, and cytoplasm

In which of these cells would you most expect to find chlorophyll?

• The cells on the left

• The cells on the right

• Both cell types

• Neither cell type

This type of cell is found in males and is responsible for reproduction.

• sperm cell
• egg cell
• muscle cell
• nerve cell

How does a stem cell become a muscle or nerve cell

• activation of different genes

• fertilization of gametes

• mitosis

• meiosis

What causes differentiation?

• The DNA is different in each type of cell.

• Some cells have more or less DNA than others.

• Only specific genes in the DNA are activated.

In embryonic development,  the process by which cells specialize is called

• differentiation
• morphogenesis
• cell division
• endoplasmic reticulum

Cancer is...

• Uncontrolled cell growth

• Normal cell growth

• A protein

• A cell cycle regulator
