Plastids and its types for class 8th

Plastids and its types for class 8th easy and in brief

1. PLASTIDS AND ITS TYPES MADE BY SAMRIDDHI BHANSALI

2. Plastids is a membrane bound organelle found in the cells of plants, algae, and some other Eukaryotic organisms. Plastids was discovered by and named by Ernst Haeckel, but A.F.W. Schimper was the first to provide a clear definition. Plastids are the site of manufacture and storage of important chemical compounds used by the cell of autotrophic eukaryotes INTRODUCTION TO PLASTIDS

3. Plastids Occur in most plant cells. Absent in animal cells. Plastids have own DNA and Ribosomes Cell organelle = Plastids

4. Chromoplasts (coloured plastids) - They are found in fruits, flowers, roots, and senescent leaves. The colour of these plant organs is associated with the presence of pigments, apart from chlorophyll Chromoplasts impart colour to flowers and fruits. Leucoplasts (white and colourless plastids) Primary organelles Store starch, oils and protein granules PLASTIDS ARE DIVIDED INTO 3 PARTS

5. LEUCOPLASTS POTATO

6. Chloroplasts Chloroplasts are organelles found in plant cells Also in eukaryotic algae that conduct photosynthesis. The kitchen of the cell Helps in photosynthesis Contain Chlorophyll pigment Plastids parts

7. Chloroplasts. Solar energy. Manufacture food photosynthesis Chromoplasts impart colour to flowers and fruits. Leucoplasts store food. Cell Organelles: Plastids Functions
