FAQs on Fun Video: Introduction to Eukaryotes Video Lecture - NEET

1. What are eukaryotes and how do they differ from prokaryotes?
Ans. Eukaryotes are organisms that have cells with a nucleus enclosed within a membrane. They also have other membrane-bound organelles, such as mitochondria and endoplasmic reticulum. In contrast, prokaryotes are organisms that lack a nucleus and membrane-bound organelles. Eukaryotes are typically larger and more complex than prokaryotes.
2. What are the main characteristics of eukaryotes?
Ans. Eukaryotes are characterized by having a nucleus that contains their genetic material, DNA. They also have membrane-bound organelles, including mitochondria, endoplasmic reticulum, and Golgi apparatus. Eukaryotic cells are generally larger and more complex than prokaryotic cells, and they can be found in a wide range of organisms, including plants, animals, fungi, and protists.
3. How do eukaryotes reproduce?
Ans. Eukaryotes can reproduce through both asexual and sexual reproduction. Asexual reproduction includes processes such as binary fission, budding, and fragmentation. Sexual reproduction involves the fusion of gametes, which are specialized cells that carry genetic information. This fusion creates offspring that inherit genetic material from both parents.
4. What are some examples of eukaryotes?
Ans. Examples of eukaryotes include humans, animals (such as dogs, cats, and birds), plants (such as trees, flowers, and grass), fungi (such as mushrooms and yeasts), and protists (such as amoebas and algae). These organisms encompass a wide range of sizes, shapes, and lifestyles.
5. How do eukaryotes obtain energy for their cellular processes?
Ans. Eukaryotes obtain energy through various processes, including photosynthesis and cellular respiration. Photosynthetic eukaryotes, such as plants and algae, use sunlight to convert carbon dioxide and water into glucose and oxygen. Non-photosynthetic eukaryotes, including animals and fungi, obtain energy by breaking down organic molecules through cellular respiration, which produces ATP (adenosine triphosphate) as an energy source.
