select all the true statements
in animal cells, lysosomes break down waste and worn - out cell parts.
both plant and animal cells can have endoplasmic reticulum.
the nucleus of a plant cell contains the chromosomes but not the vacuole.

Explanation:

• In animal cells, lysosomes break down waste and worn - out cell parts: Lysosomes are membrane - bound organelles in animal cells that contain digestive enzymes. These enzymes can break down various substances such as waste materials, foreign particles, and worn - out cell components through a process of hydrolysis.
• Both plant and animal cells can have endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranes. There are two types: rough ER (with ribosomes attached) and smooth ER (without ribosomes). Both plant and animal cells have ER. The rough ER is involved in protein synthesis (as ribosomes are the sites of protein synthesis), and the smooth ER is involved in lipid synthesis, detoxification (in liver cells, for example), and calcium storage.
• The nucleus of a plant cell contains the chromosomes but not the vacuole: The nucleus is the control center of the cell. It contains the genetic material in the form of chromosomes (DNA wrapped around proteins). A vacuole is a separate organelle. In plant cells, there is usually a large central vacuole that stores water, nutrients, and waste products. It is not located within the nucleus.

Answer:

• In animal cells, lysosomes break down waste and worn - out cell parts.
• Both plant and animal cells can have endoplasmic reticulum.
• The nucleus of a plant cell contains the chromosomes but not the vacuole.
