PLant Structure

In this project I was given three steps to describe a plant structure, how does transport in angiosperms works, and the reproduction in angiosperms.

Plant structure

The roots of a plant are anchor in the soil, which makes it better to absorb mineral, and water to store food. What it also consist of is a palisade mesophyll is a tissue having many packed cylindrical cells. Which differentials the upper epidermis that is a run on of a layer of cells covered by a thick waxy cuticle. This helps the water not get lost, Now the lower epidermis is in a breezier position that why it carries a thinner waxy cuticle. The most talk about tissues of a leave are the xylem and phloem. First the xylem is like a thin straw which water goes upward from the roots to reach the leave this action is called transpiration steam. The heat of the environment gives energy for evaporation of the water from the cell walls. Once the water evaporates it is replaced with water from xylem in the leave. Now the phloem transport all goods like amino acids inside the plants. The process is called active translocation this is, because the sugars and amino acids load into the phloem and parts of the plant that are called sources. Sources are parts of the plant where photosynthesis is occurring. It also involves a stoma which is a piece that enables CO2 for photosynthesis to diffuse. In conclusion main parts of a leave are the blade or lamina

Transport in angiosperms

Angiosperms are flowering plants which forms seeds inside a protective chamber called ovary. Angiosperms are placed in a single division that are split into two classes monocotyledones, and dicotyledones. One of the reasons why the xylem became more specialized during the time period of angiosperm it was for transporting cells during their angiosperm evolution. Cells conduct water in confeirs that are tracheids. Tracheids is in elongated tapered cell that functions in both mechanical support and the movement of water up to the plant. Angiosperm have shorter wider vessels that evolved from tracheids. The xylem of angiosperm is reinforced by a second cell type. The greatest factor in the rise of angiosperm was the evolution of a flower.

Reproduction in angiosperm

A flower is a reproductive structure of an angiosperm, many angiosperm insects and other animals transfer pollen from one flower to female sex organs on to another flower. This makes pollination less random a flower is compressed of many circular ridges sepals, petals, stamens, and carpel. The sepals and petals, I find very interesting see they are sterile and many parts of a flower. What this mainly means is hat they are not involved in reproduction, others are stamens and carpel that are reproductive organs. The stamen is very important to know, being that it has a stalk called filament which is a terminal sac, the anther were pollen is produced. Next a style leads to the ovary which developed into seeds after fertilization. Example running a baseball field you get from one base to the other.
