Question

Complete the lifecycle with genetic information (N/2N), a process (mitosis/meiosis) and the correct name of the cell or structure. The events occur in a clockwise direction.

(5pts) fill in the blank spots of the generalized plant life cycle.


GAMETOPHYTE (___)
(_________)
(mitosis)


______________ __________________ (N)
single cell (N)


FERTILIZATION



(_________) _____________ single cell


SPOROPHYTE ( 2N )

Answer 1

Here’s how you can complete the lifecycle with the relevant genetic information (N/2N), process (mitosis/meiosis), and the correct names of the cells or structures:

1. **GAMETOPHYTE (N)**
(mitosis)

2. **GAMETES (N)**
(fertilization)

3. **ZYGOTE (2N)**
(meiosis)

4. **SPOROPHYTE (2N)**

So, the completed cycle would look like this:

```
GAMETOPHYTE (N)
(mitosis)

GAMETES (N) ______________ (N)
single cell (N)

FERTILIZATION
ZYGOTE (2N) __________________ (2N)

SPOROPHYTE (2N)
```

This structure captures the alternation of generations typical of plant life cycles, with the sporophyte (2N) undergoing meiosis to produce haploid gametes (N) that can fertilize to form a diploid zygote (2N), which then grows into a new sporophyte.
