This element covers the role of water in plants, the process of water uptake and movement through the plant, transpiration stream and water-loss through the leaf R2101 – water movement in plants AO2: the impact of environmental factors on water uptake to include: Soil moisture (obvious really), temperature, relative humidity (affects the water loss at the… Continue reading Unit 1, Topic 1, Element 7 – Movement of water through the plant

Unit 1, Topic 1, Element 6 – Photosynthesis and Respiration
This section deals with the concept and importance of photosynthesis and respiration for plant growth. Photosynthesis is here: R2101 – Photosynthesis Respiration is here: R2101 – Respiration AO2 - the law of limited factors and horticultural implications in specific contexts like growing in a greenhouse or conservatory are covered in R2102 Photosynthesis. AO3: You are… Continue reading Unit 1, Topic 1, Element 6 – Photosynthesis and Respiration
Unit 1, Topic 1, Element 5 – Pollination & Fertilization
This element is about the processes of pollination and the functions of plant parts involved in pollination and fertilization. Parts of flowers involved in pollination: peduncle, receptacle, sepals, petals, stamen, anther, filament, pollen grain, stigma, style, ovary, ovule. Drawn here: R2101 – Flowers, fruits and seeds Agents of natural pollination (bees, moths flies and birds), wind… Continue reading Unit 1, Topic 1, Element 5 – Pollination & Fertilization
Unit 1, Topic 1, Element 4 – Internal Plant Structures
You need to know the characteristics, arrangement, function and horticultural importance of: Root: xylem, phloem, cambium, epidermis, endodermis. R2101 – Roots Stem: xylem, pholem, cambium, epidermis. R2101 – stems but you don't need the adaptations here. R2101 – Plant Classification, structure and function the dicotyledon stem. Leaf: xylem, phloem, epidermis, lamina, stomata, palisade, spongy mesophyll. R2101… Continue reading Unit 1, Topic 1, Element 4 – Internal Plant Structures
Unit 1, Topic 1, Element 3 – external parts of plant
This element covers the characteristics and functions of: Roots - R2101 – Roots Stems - R2101 – stems Leaves - R2101 – leaves Flowers - R2101 – Flowers, fruits and seeds You will need to be able to explain how plant structures are used to identify and describe species, and also how external structures support function… Continue reading Unit 1, Topic 1, Element 3 – external parts of plant
Unit 1, Topic 1, Element 2 – Lifecycle Adaptations
There are some definitions regarding plant lifecycle to learn, which are here: R2101 definitions The advantages of having lifecycle adaptations is to include: exploiting short growing season avoiding extreme weather ecological niches growth in less favourable conditions To get the AO3 outcome, you will need to demonstrate the impact of plant lifecyles on biodiversity, plant… Continue reading Unit 1, Topic 1, Element 2 – Lifecycle Adaptations
Unit 1, Topic 1, Plant Science 1
The scientific naming of plants is detailed here: R2101 plant name. This covers taxonomy, family, genus, species, cultivars and hybrids. The major plant groups are outlined here: R2101 plant classification. Some extra groups that were not required in the old-style exam are: Pteridophyta = vascular plants that have roots, stems, leaves and reproduce through spores… Continue reading Unit 1, Topic 1, Plant Science 1
