Question

Prepare two correctly matched pairs from the given terms. ( (Ommatidia, Cardiac tissue, Intercalated disc, Malpighian-tubules, Sense organ, Goblet cell)

Answer 1

Answer:

Sense organ - upper lip

Excretory organ - Digestive glands

Answer 2

Answer:

1. Ommatidia - Sense organ
2. Cardiac tissue - Intercalated disc

Explanation:

1. Ommatidia -

• Components known as ommatidia make up the compound eyes of arthropods such as insects, crustaceans, and millipedes.
• A collection of pigment and support cells surround a group of photoreceptor cells in an ommatidium.
• A clear cornea is placed over the ommatidium's outer portion.
• One axon bundle (often made up of 6–9 axons, depending on the number of rhabdomeres) innervates each ommatidium, supplying the brain with one picture element. These distinct visual components combine in the brain to create an image.

   2. Cardiac tissue -

• Microscopic characteristics that can be used to identify heart muscle include intercalated discs or Eberth lines.
• Individual heart muscle cells (cardiomyocytes) that are joined by intercalated discs to form a single functional syncytium make up cardiac muscle.
• Due to the fact that intercalated discs are a component of the sarcolemma of the cardiac muscle, they also have gap junctions for depolarization between muscle fibers and desmosomes that hold the fibers together during cardiac muscle contraction.
