Cell Structure and Function Quiz

Study Notes

Cells are the basic units of life. All living organisms are made of one or more cells.
Cells are the basic units of structural and organizational biology in all living organisms.
All cells come from pre-existing cells.

Animal cells are typically smaller and more irregular in shape compared to plant cells.
Plant cells tend to have a boxy or rectangular shape, and they have a cell wall.
Animal cells do not have a cell wall.
Animal cells may have multiple, small vacuoles, while plant cells have one large central vacuole.
Plant cells contain chloroplasts, which are crucial for photosynthesis. Animal cells do not have chloroplasts.
Both plant and animal cells have mitochondria and other membrane-bound organelles.

Organelles are specialized structures within cells that perform specific functions.
Examples of organelles include the nucleus, mitochondria, chloroplasts, vacuoles, endoplasmic reticulum, and ribosomes.
The nucleus contains the cell's DNA, which controls cell activities.
Mitochondria are responsible for cellular respiration, producing energy for the cell.
Chloroplasts are found in plant cells and are vital for photosynthesis.
Vacuoles store water, nutrients, and waste products.
The endoplasmic reticulum and ribosomes play roles in protein synthesis and transport.

Unicellular organisms consist of a single cell, while multicellular organisms have multiple specialized cells organized into tissues, organs, and organ systems.
Unicellular organisms, like Amoeba and Paramecium, are single-celled organisms that perform all life functions within a single cell
Multicellular Organisms have different cells with specialized roles, tissues, organs, and systems. For example, animals have a digestive system, respiratory system, and more.
