A1.2 - Animal and Plant Cells

In Human and Social Biology, a cell is best described as:

Which cell structure acts as the control centre, containing the genetic material?

Which structure is present in a typical plant cell but not in a typical animal cell?

Which structure is found in both onion epidermis cells and human cheek cells?

What is the main function of the cellulose cell wall in plant cells?

In both plant and animal cells, mitochondria are important because they:

A student notices that plant cells under the microscope appear more box-like than animal cells. This is mainly because plant cells have:

A student prepares a slide of her cheek cells and another of onion epidermis cells. Under the microscope, she sees a thick outer boundary around the onion cells but not around the cheek cells. This thick outer boundary is the:

Which row shows a cell structure correctly matched with its main function?

A potted bougainvillea plant is left unwatered on a hot day in Trinidad and begins to wilt. At the level of the plant cells, which change best explains the wilting?

Red blood cells placed in a very concentrated salt solution shrink. Which statement best explains this observation?

Which combination of features would you expect to find in a leaf cell from a healthy breadfruit tree in Jamaica?

During sports day at a secondary school in Barbados, an athlete's leg muscles require a lot of energy to run the 400 m race. Which cell structure in the muscle cells is working harder to supply this energy?

Many young herbaceous plants, such as callaloo, stand upright when well watered. Which statement best describes the role of the large central vacuole in these plants?

A breadfruit tree in St Vincent develops pale yellow leaves after being kept in deep shade for several weeks. At the cellular level, this change is most likely due to:

Four cells are described below: I. Has cell membrane, cytoplasm, nucleus, mitochondria, no cell wall. II. Has cell membrane, cytoplasm, nucleus, mitochondria, cell wall, chloroplasts. III. Has cell membrane, cytoplasm, nucleus, cell wall, no chloroplasts. IV. Has cell membrane, cytoplasm, no nucleus, cell wall. Which cell is most likely a typical animal cell?

Some poisonous chemicals damage the cell membrane of human liver cells. Which sequence of events is most likely to occur after serious damage to the cell membrane?

If both a plant cell and an animal cell are placed in pure water, which statement best compares what happens to them?

Which sequence correctly lists the structures a drop of water passes through as it moves from the outside into the cytoplasm of a typical plant cell?

Some people inherit a condition in which their cells have fewer functioning mitochondria. Which symptom would best support this diagnosis?

Which pair of statements about plant and animal cells is correct?
