Can someone help me with these?
5. Make proteins. Some ribosomes are "free" while others are attaches to the ectoplasmic reticulum.
A. Nucleus
B. Mitochondria
C. Ribosomes
D. Golgi complex
8. Contain digestive enzymes that break down waste and foreign invaders in the cell.
A. Vacuole
B. Chloroplast
C. Lysosome
D. enzyme
I got the correct answers without any help. The correct answers are both C.
To answer these questions, we need to identify the organelles involved in each function described.
5. Make proteins. Some ribosomes are "free" while others are attached to the endoplasmic reticulum.
To find the answer, let's look at the options provided:
A. Nucleus - The nucleus contains the genetic material, but it does not directly participate in protein synthesis.
B. Mitochondria - Mitochondria are responsible for cellular respiration and producing energy, not protein synthesis.
C. Ribosomes - Ribosomes are responsible for protein synthesis. They can be either free in the cytoplasm or attached to the endoplasmic reticulum.
D. Golgi complex - The Golgi complex is involved in processing and packaging proteins but not in their initial synthesis.
Therefore, the correct answer is C. Ribosomes.
8. Contain digestive enzymes that break down waste and foreign invaders in the cell.
Let's review the options:
A. Vacuole - Vacuoles are storage sacs in plant cells, but they do not specifically contain digestive enzymes.
B. Chloroplast - Chloroplasts are responsible for photosynthesis and do not contain digestive enzymes.
C. Lysosome - Lysosomes are organelles that contain digestive enzymes and are involved in breaking down waste materials and foreign invaders.
D. Enzyme - Enzymes are not organelles but proteins that act as catalysts for various chemical reactions. They are not specific to digestion.
Hence, the correct answer is C. Lysosome.
If you ever need to answer similar questions in the future, be sure to analyze the functions described and consider the specific organelles responsible for those functions.
