B) Eukaryotic cells have more intracellular organelles than prokaryotes. C) Prokaryotes are not able to carry out aerobic respiration, relying instead on anaerobic metabolism D) Prokaryotes are generally larger than eukaryotes. 5) Which structure is common to plant and animal cells? A) chloroplast B) central vacuole C) mitochondrion D) centriole 6) Which of the following is present in a prokaryotic cell? A) mitochondrion B) ribosome C) chloroplast D) ER
Explanation / Answer
Answer:
1). A) mitochondrion
2). D). An endoplasmic reticulum
Explanation: Prokaryotic cells do not have membrane bound organelles.
3). C). SUrface to volume ratio
4). B). Eukaryotic cells have more intracellular organelles than prokaryotes
Explanation: Prokaryotic cells have ribosomes, nucleoid & plasmid. But they do not have mitochondria, chloroplast, endoplasmic reticulum, golgi complex, etc. All of these organelles found in eukaryotic cells.
5). C). Mitochondrion
6). B). Ribosomes
