Meiosis In Lily Anther

Slides reveal the developmental stages of pollen from sporogenous tissue to pollen tetrads. Lily anther cell meiosis.

Meiosis

Prophase 1 of meiosis.

Meiosis in lily anther. Introduction in this study meiosis will be studied as it occurs in the development of mature pollen grains of flowering plants. If an anther contains pollen it is usually possible to squeeze the loose grains out of the loculi during the staining process so that a squash of the anther wall produces gametogenic cells. Luckily in the early stages of meiosis all the cells in the sac are in the same stage.

We will now begin to identify the different stages of meiosis. Lily anther pollen tetrads. A is for mature pollen b is for pollen tetrads c is for 1st meiotic division and d is for 2nd meiotic division.

What happens in image 1. The four cells that result from meiosis in the lily anther are microspores and can be seen as four cells attached together a tetrad of cell. The phases in the second half of meiosis occur rapidly.

Contents of this slide set typical sporogenous lily anther. Meiosis in the anther starts with the diploid microsporocyte. The cross section of the lily anther to the left is in the early stages of meiosis.

We are carrying out root tip squash as standard but the lily anther is the first time. Was created by honeyb060674 has anybody carried out this practical for year 12 13. Besides we should be able to observe identify and draw the stages of meiosis in a lily s anther.

Nuclear membrane breaks down chromatin condenses spindle forms and attaches to kinetochores. The pollen grain in turn will produce sperm nuclei by mitosis. The manufacture of pollen by an angiosperm requires meiosis to occur producing haploid nuclei.

Lily anther 1st division. Nuclear membrane breaks down chromatin condenses spindle forms and attachs to kinetochores. Each nucleus has a diploid number of duplicated chromosomes.

Lily anther cell meiosis study. Lily anther early prophase. Lily anther 2nd division.

A distinct layer of cell wall is laid down between the two phases of meiosis in lily. Each of these is considered a type of spore and will become a pollen grain. Meiosis in a lily s anther objectives to observe and identify the stages of meiosis in a lily s anther.

Terms in this set 19 image 1 is an image of what. The chromosomes undergo a separation of chromatids during the second half of meiosis in a cycle similar to mitosis except for recombination between homologous chromosomes. Link to view of telophase ii cell of lily anther.

Discussion the first phase of cell cycle interphase was observed in stages 2 and 5 of figure 1. Lily anther squash to show meiosis. Microtubules align homologous chromosome pairs along metaphase plate.

Examine meiosis in a lily anther cross section with this 5 slide set. The observations are as follows. And then meiosis were observed in lily anther figure 2 with 4 different samples.

These cells are still attached in the microsporangium.
