Question

an amoeba releases waste and water through its body surface to the surroundings as shown. which statement describes the process of water and waste removal as shown in the image? a. an amoeba contains a cell wall that controls the release of water and waste. b. an amoeba has various tissues that work together to remove water and waste through the cell membrane. c. an amoeba has specialized organs that store and release water and waste from its body. d. an amoeba packages water and waste in membrane - bound vesicles, which are released outside its body.

Explanation:

• Option A: Amoebas do not have a cell wall. Cell walls are typically found in plant cells, fungi, and some bacteria.
• Option B: Amoebas are single - celled organisms and do not have tissues. Tissues are groups of cells that work together and are found in multicellular organisms.
• Option C: Amoebas are single - celled and do not have organs. Organs are made up of different tissues and are a feature of multicellular organisms.
• Option D: Amoebas use membrane - bound vesicles (such as contractile vacuoles for water regulation in some cases) to package and release waste and excess water. This is a common mechanism in single - celled organisms for excretion.

Answer:

D. An amoeba packages water and waste in membrane - bound vesicles, which are released outside its body.
