Inside the Cell

Membrane that surrounds all living cells and controls the passage of substances between the cell and the organelles.

• cell membrane

• chloroplasts

• cytosol

Small organelles in plant cells that contain a green pigment called chlorophyll.

• chloroplasts

• chromosomes

• mitochondrion

Filamentous structures of different sizes and shapes that are found in the nucleus of eukaryotic cells; they are made up of DNA, RNA, and proteins.

• chromosomes

• nucleus

• DNA

The cell’s living material, except for the nucleus and large vacuoles, where many metabolic activities take place.

• cytoplasm

• cellular membrane

• chloroplasts

The soluble portion of the cytoplasm; this is where most cell organelles are located.

• cytosol

• nucleus

• mitochondrion

A nucleic acid found in chromosomes that contains the genetic information of organisms.

• DNA

• RNA

• nucleus

Cell with a nucleus surrounded by a nuclear membrane.

• eukaryotic cell

• prokaryotic cell

A special region of the smooth endoplasmic reticulum (smooth ER) that collects and distributes substances produced in the cell.

• Golgi apparatus

• nucleus

• mitochondrion

Organelle of all plant and animal cells where substances entering the cell are broken down for energy.

• mitochondrion

• cell membrane

• chloroplasts

Organelle in plant and animal cells that contains the genetic information [DNA] and therefore, controls the activities of the cell.

• nucleus

• nucleolus

• DNA
