(B)TENDON and ligaments are dense connective tissues.The tendon cells are modified fibroblasts. Tendons occur at the ends of skeletal muscles, and serves to attach them strongly to bones.
LIGAMENTS are found in joints. Ligaments connect bones at joints and hold them together in position. The matrix is densely crowded with collagen fibres running in different directions and with some elastin fibres inbetween. Some flat elongated ligament cells are seen inbetween the fibres.

(c)Structurally, plant and animal cells are very similar because they are both eukaryotic cells. ... Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.

1)Parenchyma - thin walled ,

- found in soft parts of

the plant

Sclerenchyma - thick walls

-found in stems and

veins of the leaves

2)tendon - which connects bone to

muscle

Ligament - which connects bone to

bone

3)plant cell - consist of cell wall

- contains plastides

-large vacuole

-no Centrosomes

-cytoplasm is not so

dense

Animal cell - no cell wall

- no plastides

- no such large vacuole

-Centrosomes are present

- cytoplasm is denser and

more granules
