Answer 1

Answer:

Allows the growth of long bones

Hyaline cartilage

Hyaline cartilage allows growth of long bones by endochondral ossification, which involves replacement of the initial hyaline cartilage models to bony tissue. This model is glass-like and formed from the combination of chondroitin sulfate and type II collagen. Aside from bone growth, it's also seen in joints, anterior ends of ribs, upper respiratory tract like larynx, trachea, and bronchi.

Intervertebral disks, pubic symphysis

Fibrocartilage

Fibrocartilage is composed of Type 1 and 2 collagen, which contributes to the toughness of this tissue. It is present in these sites due to the dynamic nature of these body parts. This cartilage is able to withstand a certain amount of shear and compressive forces. Along with the hyaline cartilage, it also promotes bone formation.

External ear, epiglottis, and auditory tubes

Elastic cartilage

Elastic cartilage, or yellow cartilage contains a number of elastic fiber and collagen. Elastin is the primary protein in this tissue, which contributes to the elasticity and flexibility of the above body parts.  If observed under the microscope, its structure is same to hyaline but has numerous yellow elastic fibers present, which appear as a dark streak.

Outer portion of all bones

Compact bone

Compact bone or cortical bone, is the substance used to form the solid outside structure of the bones.

Inside skull bones, vertebrae, and sternum

Spongy bone

Cancellous bone, spongy bone, or trabecular bone is mostly found in the long bones, covered by compact bone. The bone is sponge-like in structure because it houses the blood vessels inside the bones.

Transports oxygen, carbon dioxide, and other substances

Blood

Blood is a connective tissue composed of red blood cells (erythrocytes), white blood cells (leukocytes), and platelets. It also connects bodily systems by transporting nutrients, hormones, and chemical messengers, etc.

Produces new blood cells and stores lipids

Bone marrow

Bone marrow is found within the spongy bone which houses the young blood cells until they are ready for use by the body or also called hematopoiesis.

Capable of strength with stretching and recoil in several directions

Dense irregular elastic connective tissue

For dense irregular elastic connective tissue, the elastic fibers are arranged randomly. This makes the organ stretchable and flexible in all directions and able to return to its original shape. An example of this is the dermis.

Tensile strength capable of withstanding stretch in all directions

Dense irregular collagenous connective tissue

Its fibers are also arranged in random but  with fibrous tissue. It is also flexible and tougher compared to dense irregular elastic connective tissue. It is usually found in fibrous capsule of joints and muscle fascia.

Vocal folds and ligaments between vertebrae

Dense regular elastic connective tissue

For dense regular elastic connective tissue, the elastic fibers are arranged in parallel. It enhances the present tensile strength to a specific direction wherein the fiber is oriented.

Tendons and ligaments

Dense regular collagenous connective tissue

For dense regular collagenous connective tissue, the collagen fibers are also arranged in parallel. Tensile strength and resistance is enhanced to a specific direction wherein the fiber is oriented. The role of these tissues is to transfer forces to the bone to avoid injury.

Provides superstructure for lymphatic tissues

Reticular tissue

Reticular tissue is found mostly with numerous amounts of cells. They are composed of Type 3 collagen fibrils and is net-like in appearance, also called "reticulum" due to the fiber arrangement (reticulin). They act as a scaffold of the organ/s they cover.

Energy storage

Adipose tissue

Adipose tissue is composed of fat cells or adipocytes. It also functions to insulate and cushion the body from hard surfaces.

Epithelial basement membrane sits on this

Loose connective tissue

Loose connective tissue or areolar connective tissue, contains a lot of cells, ground matter, and spaces in between it, coining the "loose" in its name. Fibroblasts, collagen fibers, and matrix, etc., are found in almost every part of the body. This helps in keeping the organs in place and some slight tough protection.

Precursor to adult connective tissues

Mesenchymal tissue

Mesenchymal tissue forms the body’s connective tissues, from bones, cartilage, to the organ systems. It is found abundant in the development of fetal tissues.

Umbilical cord of the newborn

Mucous connective tissue

Mucous connective tissue is also found during development of the embryo. Due to mucoproteins, it resembles a mucus-like substance, as in Wharton's jelly found in the umbilical cord and vitreous in the eyeball.
