Life sciences grade 10 memorandum
The topics in Grade 10 life science In this lesson on Molecules for Life we focus on:
- inorganic compounds,
- organic compounds
- food tests.
In this lesson on Cell Division we focus on the following: What is cell division, the phases of mitosis, the role of mitosis, chromosome structure as well as take a look at cancer. The life sciences comprise fields of science involving the study of living organisms such as plants, animals and humans. While biology remains the centerpiece of the life sciences, technological advances in molecular biology and biotechnology have led to a burgeoning of specializations and new interdisciplinary fields.

Lesson 1: Molecules of Life
In this lesson on Molecules for Life we focus on: inorganic compounds, organic compounds & food tests.
Lesson 2: Cells – The Basic Units of Life
In this lesson on Cells – The Basic Units of Life, we focus on the following: Cell structure, the functions of different parts of cells, diffusion as well as osmosis
Lesson 3: Cell Division – Mitosis
In this lesson on Cell Division we focus on the following: What is cell division, the phases of mitosis, the role of mitosis, chromosome structure as well as take a look at cancer.
Lesson 4: Plant Tissues – Organ Leaf
In this lesson we take at look at Plant Tissue. We touch on levels of organisation, the definition of a tissue, types of plant tissues as well as plant organs.
Lesson 5: Animal Tissues
In this lesson we take a close Animal Tissue. We touch on topics such as the types of animal tissue as well as applications of IKS and biotechnology.
Lesson 6: Support and Transport in Plants I
In this lesson we take a close look at Support and Transport in Plants. In this session we focus specifically on the anatomy of dicotyledonous plants.
Lesson 7: Support and Transport in Plants II
In this lesson we take another look at Support and Transport in Plants II. We focus on the relationship between water loss and leaf structure factors that affect the rate of transpiration. We look at the uptake of water and minerals into xylem in roots. We look at transport of water and minerals to the leaves. Finally, we consider the translocation of manufactured food from leaves to other parts of the plant.

Lesson 8: Support Systems in Animals I
In this lesson we take a look at Support Systems in Animals I. We consider examples, advantages and disadvantages of hydrostatic skeletons, exoskeletons as well as endoskeletons. We look at the human skeleton – the axial and appendicular skeleton. We consider the functions of the skeleton as well as the structure of the long bone.
Lesson 9: Support Systems in Animals II
In this lesson we continue to take a close look at Support Systems in Animals and we discuss in depth the the human skeletal system
Lesson 10: Transport Systems in Mammals (Human) I
In this lesson we take a close look at Transport Systems in Mammals. In this lesson we touch on the blood circulation system, the direction of blood flow & circulation as well as the mechanism for controlling the cardiac cycle and heart rate.
Lesson 11: Transport Systems in Mammals (Human) II
In this lesson we continue to look at Transport Systems in Mammals. In this lesson we focus on blood vessels, the lymphatic system and diseases of the heart and circulatory system.
Lesson 12: Biospheres to Ecosystems I
In this lesson on Biospheres to Ecosystems I we focus on biospheres & biomes of Southern Africa. We look at terrestrial and aquatic biomes of Southern Africa as well as how climate, soil and vegetation influence the organisms found in each. Finally, we look at the location of the different biomes in South Africa.
Lesson 13: Biospheres to Ecosystems II
In this lesson on Biospheres to Ecosystems II we focus on: The environment, abiotic and biotic factors, energy flow and trophic levels, cycles as well as Ecotourism.
Lesson 14: Biodiversity and Classification
In this lesson on Biodiversity & Classification we focus on: Biodiversity of the Earth & South Africa, the history of classification as well as taxonomic levels of classification.
Lesson 15: History of Life on Earth
In this lesson on the History of Life on Earth we focus on: Terminology and definitions, life’s history, mass extinctions, key events in the history of life (SA) as well as fossil tourism.
