Which organelle controls cellular activity comparable to the way the brain controls body activity?

• Cytoplasm

• Cell membrane

• Vacuole

• Nucleus

Cells require a structure that regulates the transfer of material in and out of the cell. This structure is the -

 

• cell membrane.

• mitochondria.

• nucleus.

• chloroplast.

Which human body system performs a function similar to what the mitochondria perform for the cell?​ ​​ (a)  

• Digestive system
• Integumentary system
• Reproductive System
• Nervous System

Cells need a structure to separate their genetic material from the rest of the cell. This structure is the -

• cell membrane

• vacuole

• cytoplasm

• nucleus

Cells require a thick, jelly-like substance that holds organelles in place inside the cell. This substance is known as -

• chlorophyll

• DNA

• mitochondria

• cytoplasm

The smallest units of life that make up all living things are --

• tissues

• cells

• organs

• organ systems

The stomach, small intestine, and large intestine are all organs. When they work together to process food, they form a functional unit known as -

• an organism

• a system

• a tissue

• a cell

A collection of cells with similar function forms -

• an organ

• a tissue

• an organism

• an organ system
