(b) Mitochondria, X-amyloplasts , Y-aleuroloplasts, Z-elaioplasts
(C) Lysosomes, X-elaioplasts , Y-aleuroloplasts, Z-amyloplasts (d)Endoplasmic reticulum, X-amyloplasts , Y-aleuroloplasts, Z-elaioplasts

Answer 1

Answer:

MITOCHONDRIA

Explanation: b)

Answer 2

The cell organelles that contain their own DNA and ribosomes are (b) mitochondria, X-amyloplasts, Y-aleuroloplasts, Z-elaioplasts and plastids.

Explanation:

• Mitochondria and plastids such as chloroplast have their own DNA and ribosomes, allowing them to synthesis proteins and replicate independently of the nucleus.
• Mitochondria are membrane-bound organelles that are separated by two membranes. The creation of energy is the primary function of mitochondria, which is why they are known as the cell's powerhouse.
• Mitochondria and plastids are plant organelles that carry genetic material, DNA and ribosomes in a plant cell. Mitochondria are rod-shaped organelles found in all animal and plant cells that are primarily responsible for power gene expression.
