Biology 102 Midterm Exam Review 2023-24

What is the term for the fundamental concept of biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cells.

• Cells

• Cell Theory

• Prokaryote Theory

• Eukaryote Theory

The structure labeled H in the image is a cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis.

• Cytoplasm

• Ribosome

• Nucleus

• Vacuole

The Structure labeled F in the image is cell organelle that converts the chemical energy stored in food into compounds (ATP) that are more convenient for the cell to use.

• Mitochondria

• Ribosome

• Chloroplast

• Nucleus

The structure labeled G in the image the organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.

• Golgi Apparatus

• Smooth Endoplasmic Reticulum

• Rough Endoplasmic Reticulum

• Mitochondria

The structure labeled A in the image is a ribbon like organelle that is studded with ribosomes and engages in protein modification

• Rough Endoplasmic Reticulum

• Smooth Endoplasmic Reticulum

• Mitochondria

• Golgi Appartus

The structure labeled E in the image is the structure that contains the cell's genetic material in the form of DNA.

• Nucleolus

• Chromosome

• Centriole

• Nucleus

This structure is a cell organelle that stores materials such as water, salts, proteins, and carbohydrates. Plants have a large central one that stores water and helps the cell keep its shape.

• Vacuole

• Lysosome

• Nucleus

• Mitochondria

______ __________requires NO energy because the movement of molecules from high to low concentration allows molecules to move with their concentration gradient.

• Endocytosis

• Active transport

• Passive transport

• Pinocytosis

The movement of molecules from an area of higher concentration to an area of lower concentration is called _________

• Brownian motion

• Diffusion

• Endocytosis

• Active transport

This is the term used to describe the diffusion of water through a selectively permeable membrane.

• Endocytosis

• Exocytosis

• Osmosis

• Active transport
