Cell Structure
In what ways are plant and animal cells similar?
Both have many of the same organelles (nucleus, mitochondria, ribosomes, cytoplasm, cell membrane).
How do plants convert energy during photosynthesis?
Plants convert sunlight into chemical energy (glucose) during photosynthesis.
How does the function of a vacuole in an animal cell compare to its function in a plant cell?
Plant vacuoles are large and store water for support; animal vacuoles are small and mainly store waste and nutrients.
Which best describes the mitochondrion of a cell?
The mitochondrion is the powerhouse of the cell.
Why are mitochondria important organelles?
Mitochondria are important because they produce ATP for energy.
Which structure gives support and shape to plant cells?
The cell wall gives support and shape to plant cells.
Why do plant and animal cells have mitochondria?
Both plant and animal cells need mitochondria to release usable energy from food.
Which best explains why the vacuoles in plant cells are usually larger than those in animal cells?
Plant vacuoles are larger because they store water to help maintain turgor pressure (rigidity).
How does the mitochondria function in energy production?
Mitochondria break down glucose and oxygen to produce ATP (energy).
Which structure directs the activities of the cell and can also be found in an animal cell?
The nucleus directs cell activities and is found in both plant and animal cells.
Which organelle can be found in both animal and plant cells?
Nucleus
Cytoplasm
Ribosomes
Endoplasmic Reticulum
Golgi Apparatus
Cell Membrane
Why are mitochondria important organelles?
Mitochondria are important because they make ATP, the energy currency of the cell.
What is the role of the vacuole in both types of cells?
Vacuoles store materials such as water, food, and waste.
What is the main chemical process that occurs in mitochondria?
The main chemical process is cellular respiration
Where does cellular respiration primarily occur?
Cellular respiration occurs primarily in the mitochondria.
Which organelle, found in both plant and animal cells, serves a different purpose in the two different types of cells?
Vacuole (large in plants for storage and support; small in animals for storage and waste).
Which organelle breaks down sugars to provide energy to a cell?
The mitochondria break down sugars to provide energy.
Which structure regulates what enters an animal cell?
The cell membrane regulates what enters an animal cell.
How do mitochondria contribute to cellular respiration?
Mitochondria release energy by converting glucose into ATP during cellular respiration.
What makes plant cells unique from animal cells?
Plant cells are unique because they have a cell wall, chloroplasts, and a large central vacuole.
Which cell parts are found only in plant cells?
Cell wall, chloroplasts, and large central vacuole are found only in plant cells.
Which combination of organelles is only found in plant cells?
Chloroplasts + cell wall + large central vacuole are only found in plant cells.
Why do vacuoles in plant cells have a larger capacity than in animal cells?
Plant vacuoles need a larger capacity to store water and keep the plant upright.
How do mitochondria and chloroplasts work together in plant cells to support li
Chloroplasts make glucose through photosynthesis, and mitochondria break down glucose to release usable energy (ATP) for the cell.
How do plant and animal cells differ in their energy needs?
Plant cells can make their own food (photosynthesis), while animal cells must consume food for energy.
