The worksheet you've provided is about identifying whether various reproductive events are
asexual (involving one parent) or
sexual (involving two parents), and determining whether the process involves
mitosis (for body cells, in asexual reproduction) or
meiosis (for sex cells, in sexual reproduction).
Let’s go through each event, verify the answers, and explain the reasoning behind each:
---
1. Potato Budding
-
Event: Buds are forming and growing on this potato.
-
Answer: Asexual, Mitosis
-
✔ Correct
-
Explanation: Potatoes reproduce vegetatively via buds (eyes) that grow into new plants. This is
asexual reproduction because only one parent (the potato) is involved. The new plant develops from somatic (body) cells through
mitosis, producing genetically identical offspring.
---
2. Single-cell organism: Amoeba produces 2 new same amoebas by simply dividing.
-
Answer: Asexual, Mitosis
-
✔ Correct
-
Explanation: Amoeba reproduces by binary fission, which is a form of
asexual reproduction. The nucleus divides via
mitosis, and the cell splits into two genetically identical daughter cells.
---
3. Male Rice generates pollen (as sperms) fertilize with eggs of female rice to produce seeds which can grow new rice plant.
-
Answer: Sexual, Meiosis
-
✔ Correct
-
Explanation: Pollen (male gametes) and egg cells (female gametes) combine during fertilization — this is
sexual reproduction. Gametes are formed through
meiosis, which reduces chromosome number by half to ensure proper chromosome number after fertilization.
---
4. Hens lay fertilized eggs to generate new chick.
-
Answer: Sexual, Meiosis
-
✔ Correct
-
Explanation: Chickens reproduce sexually. The hen lays an egg that was fertilized by sperm from a rooster. The sperm and egg are produced via
meiosis. The zygote develops into a chick, combining genetic material from both parents.
---
5. Place a piece of leaf of green bean in soil and regrow new green pea plant
-
Answer: Asexual, Mitosis
-
✔ Correct
-
Explanation: This is
vegetative propagation — a method of asexual reproduction where a part of the plant (like a leaf) grows into a new plant. It involves mitotic division of somatic cells, resulting in a clone of the parent plant.
---
6. Clone sheep – The New biotech can generate identical baby sheep (Dolly) from mom only. They have same genes and traits as mom.
-
Answer: Asexual, Mitosis
-
✔ Correct
-
Explanation: Cloning (e.g., Dolly the sheep) is
asexual reproduction. A nucleus from a somatic cell of the mother is placed into an egg cell, and the embryo develops using
mitotic divisions. No gametes are involved; the offspring is a genetic copy.
---
7. Black cat was born from a white mom cat and black dad cat
-
Answer: Sexual, Meiosis
-
✔ Correct
-
Explanation: The kitten results from the fusion of sperm (from black dad) and egg (from white mom). This is
sexual reproduction. Both gametes were formed via
meiosis, ensuring genetic variation.
---
✔ Final Summary:
All the answers in the worksheet are
correctly filled out.
| Event | Type of Reproduction | Cell Division Process |
|-------|------------------------|------------------------|
| 1. Potato Budding | Asexual | Mitosis |
| 2. Amoeba division | Asexual | Mitosis |
| 3. Rice pollination | Sexual | Meiosis |
| 4. Hen laying fertilized eggs | Sexual | Meiosis |
| 5. Leaf propagation | Asexual | Mitosis |
| 6. Clone sheep | Asexual | Mitosis |
| 7. Cat offspring | Sexual | Meiosis |

🔍 Key Concepts Recap:
-
Asexual reproduction: One parent → Offspring are clones → Involves
mitosis.
-
Sexual reproduction: Two parents → Gametes fuse → Involves
meiosis to produce gametes.
-
Mitosis: Produces two identical diploid cells (body cells).
-
Meiosis: Produces four genetically diverse haploid gametes (sex cells).
✔ All entries in your worksheet are accurate and well-explained. Great job!
