Plantae Kingdom Project

Extracts from this document...


The Plantae Kingdom Introduction The plantae kingdom or the 'green kingdom' consists of mosses, ferns, conifers, flowering plants and so on. It is made up of multicellular organisms and has over 250,000 species. Plants have been surviving on earth for a very long time. Without plants life on earth would be impossible. Mushroom and algae would still survive but fruits, vegetables, grains and animals come from or rely on plants for life. Most plants need light energy in order to live. Light is their source of energy and it is used for growth and development. The light energy is captured by the colourful chemicals called pigments. The pigments interact with the light and it produces the colour we see on plants, usually green which is imparted by the pigment chlorophyll. Chlorophyll is one of the most important pigments found in plants. It transfers the energy absorbed from light to the chemicals which go about storing it chemically. A plant's food is sugar, starch and carbohydrates that are all acquired from the process of photosynthesis. ...read more.


For example, some mosses can be left dried out for decades and then be re-hydrated back and allowed to have life again. They can fully recover in under an hour. The second way is called drought avoidance which is when plants develop features which reduce the loss of water or store it in their tissues. Some plants develop a condition (succulence) in which the tissues are spongy and swollen for storing water like in cacti. Classification Of Plants Plants are classified into 12 phyla or divisions which are according to their reproductive characteristics. So they are classified according to their tissue structure which determines whether they are vascular or non-vascular plants. Then are classified according to their seed structure such as whether they reproduce through naked seeds, covered seeds or spores. They are also classified by their stature where they are divided into mosses, ferns, shrubs and vines, trees and herbs. Non-Vascular Plants Mosses are non-vascular plants which mean that they cannot transport fluids through their bodies. ...read more.


After fertilization, the flower falls away and the ovary swells to become a fruit. They grow two-seeded leaves. Dicot Plants come from a phylum which includes about 200000 species. Most of the fruits and vegetables come from this phylum. Monocots start growing with a one-seeded leaf. Grass on lawns are monocots. Monocots provide us with our primary source of nutrition, supplying us and the animals we eat with grains such as corn, wheat, oats and some fruits like dates and bananas. Organelle Function Cytoplasm Transfers energy, makes things and stores food (watery solution). Cell Wall Made of cellulose, used for protection of the cell. Nucleus Essential for the cell to live. It controls the various processes which go on inside it (control centre). Vacuole Contains cell sap. Pushes the cytoplasm to the edge of the cell for support. Plasma/Cell Membrane Controls what goes in and out of the cell. Chloroplast Contains green pigment chlorophyll which is used in photosynthesis. Ribosomes Make proteins. Mitochondria Supply energy for the cell. Converts chemical energy into ATP. Endoplasmic Reticulum Transport system of the cell. Moves things around in the cell.

Response to the question

The response to the topic is done very well. The candidate outlines many features of general plants from their classification and basic function to their structure. To improve the candidate could have used the topic to go into greater detail on plants such as reasons for differences between certain plants and how they have adapted.

Level of analysis

The plants basic structure is defined well for this level. The candidate introduces the topics well and defines the different basic features of the plant kingdom. They outline different survival tactics well by outlining a number of different ways and they also provide examples of the different tactics. They also explain the classification of plants well and show a good understanding of why they are classified this way. They outline the function of organelles to a good basic level.

Quality of writing

Punctuation, grammar and spelling all to a good level. Format of the essay is clear and easy to read with good aiding diagrams.

    I expect that the solutions of higher sugar concentration will cause the greatest decrease in mass of the potato disc because the concentrations on either side of the membrane are unbalanced. The water molecules will diffuse through the semi-permeable membrane from the potato cytoplasm to the surrounding solution so that the concentrations are of equal strengths.

  2. Enzymes are biological catalysts made up from protein

    I predict this because enzymes are designed to react best at the body temperatures of the animals to which they belong. For a mammal, this is around 35-36. Catalysts are used to speed up biochemical reactions in the body. An enzyme is a protein molecule that speeds up chemical reactions in all living things.
