Biology Chapter on Cells

Differences Between Plant and Animal Cells

• Plant cells possess a cell wall and chloroplasts, while animal cells do not.
• Animal cells contain centrioles, which are absent in plant cells.

Size Orders

• Cells, tissues, organs, organ systems, organisms represent a decreasing order of size.

Cell Groups

• A group of similar cells performing a shared function is termed a tissue.

Cellular Respiration

• Cellular respiration occurs primarily in the mitochondria.

Onion Cell Parts

• Onion cell parts labelled A, B, and C typically indicate the cell wall, cytoplasm, and nucleus, respectively.

Storage Organelles

• Vacuoles are used for the temporary storage of food, water, and waste products.

Nerve Cells

• Neurons are specialized cells known as nerve cells.

Cell Membrane Function

• The cell membrane regulates the entry and exit of materials, providing protection and support for the cell.

Cell Replication

• Mitosis is the process by which cells make copies of themselves.

Multicellularity

• Multicellular organisms consist of many specialized cells that work together.

Nucleus Absence

• Prokaryotic cells, like bacteria, have no nucleus.

Prokaryotic Organelles

• Prokaryotes do not contain membrane-bound organelles, which makes the statement false.

Cell Types

• Captionless images potentially represent various types of cells, requiring context for identification.

Protein Synthesis

• Ribosomes are responsible for making proteins for the cell.
