Eukaryotic Organelles: The Structure And Function

There are many different organelles in eukaryotic cell. Some of the organelles are: the Nucleus, Mitochondria, Ribosome’s, Golgi Apparatus, Lysosome, Endoplasmic Recticulur,Cytoskeleton,Centrioles, Nucleus membrane, and Vacuole. The nucleus is the brains of the cell. The nucleus directs all activities and contains genetic material called chromosomes of DNA. The structure of mitochondria is that it is spherical in shape, and visible when cell is not dividing, and contains RNA for protein manufactor…

Plants 1 Essay

answers Plant cells and tissues 1. a. Describe the structure of a primary cell wall. b. How does a secondary cell wall differ? a. The primary cell wall consists of strands of cellulose that run parallel to each other to form the microfibrils. Various molecules including glycoprotein and pectin form crosslinks between the microfibrils. b. Compared with the primary cell wall the secondary cell wall is thicker and more rigid. The linking material is lignin which gives the secondary wall its additional…

Notes On Transport In Angiospermophytes

9.2 Transport in Angiospermophytes Roots - Function: absorb water and mineral ions from soil - Roots increase surface area in contact with soil by: o Develops an extensive, branching root system o Numerous root hair - root hairs are temporary and die away to be replaced by new ones near the growing tip of root. - Minerals required by plants for growth: o Calcium – constituent of cell wall o Magnesium – needed to make chlorophyll o Iron – required as a cofactor for many enzymes - These…

Essay on Xylem and Cells

Chapter 36 Transport in Vascular Plants Lecture Outline Overview: Pathways for Survival The algal ancestors of plants obtained water, minerals and CO2 from the water in which they were completely immersed. For vascular plants, the evolutionary journey onto land involved the differentiation of the plant body into roots, which absorb water and minerals from the soil, and shoots, which absorb light and atmospheric CO2 for photosynthesis. This morphological solution created a new problem: the need…

Osmosis And Diffusion

water with a wall dividing the water from the empty part of the container. Opening the wall would “diffuse” the water and cause it to flow into the empty part of the container. It is considered passive because it doesn't require any energy. Using the water as example for this, the water doesn't need any energy to fall into the empty space. Active transport is a way of forcefully moving molecules where you want them to go, which requires energy. An example of this would be taking the wall and wading…
