All the following statements regarding cell organelles are correct, e...
Lysosomes are single-membrane vesicles budded off from Golgi apparatus and contain digestive enzymes.
Endoplasmic reticulum consists of a network of membranous tubules and helps in transport, synthesis, and secretion.
Sphaerosomes are single membrane-bound and are associated with the synthesis and storage of lipids.
However, the statement that leucoplasts are bound by a single membrane, lack pigment but contain their own DNA and protein-synthesizing machinery is incorrect.
Leucoplasts are actually non-pigmented plastids found in plant cells. They are bound by a double membrane, not a single membrane. Leucoplasts do not contain their own DNA and protein-synthesizing machinery. Instead, they are involved in the synthesis and storage of starch, oils, and proteins.
Leucoplasts are categorized into three main types:
1. Amyloplasts: These are responsible for the synthesis and storage of starch. They are commonly found in storage tissues, such as roots, tubers, and seeds.
2. Elaioplasts: Elaioplasts are involved in the synthesis and storage of oils and fats. They are commonly found in seeds and fruits.
3. Proteinoplasts: Proteinoplasts are involved in the synthesis and storage of proteins. They are found in developing and germinating seeds.
Leucoplasts play a crucial role in the metabolism of plant cells by storing and synthesizing important molecules. They are involved in the conversion of glucose to starch, the synthesis of oils and fats, and the accumulation of storage proteins.
In summary, leucoplasts are double-membrane-bound organelles found in plant cells that are involved in the synthesis and storage of starch, oils, and proteins. They do not contain their own DNA and protein-synthesizing machinery.
Endoplasmic reticulum consists of a network of membranous tubules and helps in transport, synthesis, and secretion.
Sphaerosomes are single membrane-bound and are associated with the synthesis and storage of lipids.

All the following statements regarding cell organelles are correct, e...
Plastids are double membranous structures. Plastids are of three types: Chloroplast, leucoplast, chromoplast.
Chloroplasts contain its own DNA protein-synthesising machinery.
Leucoplast are of three types: amyloplast, proteinoplast and elaioplast. Amyloplasts can synthesize and store starch. Proteinoplasts store proteins but can not synthesise. Elaioplasts store lipids.
Leucoplasts are colourless plastids which generally occur near the nucleus in non-green cells and possess internal lamellae.
