• The Organelle

• The Nucleus

• The Tissue

• The Cell

The study of cells is called:

• Histology

• Cytology

• Cell biology

• Anatomy

General Cell: Core organelles carry out essential functions for cell survival, including harvesting energy, making new proteins, and:

• mediating DNA replication

• regulating the cell division cycle

• getting rid of waste

• performing passive osmosis

What is the cell membrane also historically referred to as?

• Karyoplasm

• Cytosol

• Plasmalemma

• Nucleoplasm

The cell membrane separates the interior of the cell from the outside environment, which is known as the:

• intermembrane space

• extracellular space

• cristae space

• cisternal space

The basic function of the cell membrane is to protect the cell from its surroundings and to:

• store hereditary material

• make ribosomes

• control the movement of substances in and out of cells and organelles

• synthesize sex hormones

What four different types of molecules is the cell membrane composed of?

• RNA, DNA, Granules, Matrix

• Water, Salt, Enzymes, Cholesterol

• Phospholipids, Cholesterol, Proteins, Carbohydrates

• Intermediate filaments, Microtubules, Secretory vesicles, Vacuoles

What is the process by which a cell moves the contents of secretory vesicles out of the cell via the cell membrane?

• Endocytosis

• Diffusion

• Osmosis

• Exocytosis

In eukaryotic cells, the cytoplasm is the material within the living cell, excluding the:

• Nucleus

• Mitochondria

• Ribosomes

• Endoplasmic Reticulum

What is the gel-like substance that is enclosed within the cell membrane and is a component of the cytoplasm?

• Nucleoplasm

• Peroxisome

• Cytosol

• Chromocentre
