Sacs are called thylakoids.Stacks are called grana.
They are called grana.Light reaction takes place there.
A saclike organ formed from the tissues of the embryo and uterus is known as the placenta. It serves as a vital interface between the mother and the developing fetus, facilitating the exchange of nutrients, gases, and waste products. The placenta also produces hormones essential for maintaining pregnancy and supporting fetal development.
The saclike membrane surrounding the heart is called the pericardium. It consists of two layers: the fibrous pericardium, which provides protection and anchors the heart, and the serous pericardium, which has two sub-layers (the parietal layer and the visceral layer) that produce pericardial fluid. This fluid reduces friction as the heart beats, allowing for smooth movement within the chest cavity. The pericardium plays a crucial role in protecting the heart and maintaining its position in the thoracic cavity.
The internal membranes found in chloroplasts are called thylakoid membranes. Thylakoid membranes house the pigments and proteins necessary for the light-dependent reactions of photosynthesis. These membranes are arranged in stacks called grana.
Thylakoid membranes. These membranes are where the light-dependent reactions of photosynthesis take place, converting light energy into chemical energy to power the process. They contain pigments like chlorophyll that capture light energy for photosynthesis.
Vacuoles
the vacuoles
A saclike structure located inside the ovary.
The scrotum is the saclike part that hangs outside the male reproductive system. It is located outside the body in order to regulate the temperature of the testes.
Deoxygenated blood is pumped through the pulmonary arteries to the alveoli, which are the small, elastic saclike structures in the lungs. In the alveoli, carbon dioxide is exchanged for oxygen during the process of respiration. This oxygenated blood is then returned to the heart to be circulated throughout the body.
The medical term for abnormal accumulation of fluid in a saclike cavity is "hydrops" or "hydrosac." This condition can occur in various body cavities or structures, leading to swelling and potential complications. Treatment typically involves addressing the underlying cause of the fluid buildup.
A bursae is a sack like structure that is filled with viscid fluid. The main purpose of the bursae sack is to protect tendons.
The saclike organs that extract waste from the blood of arthropods are called Malpighian tubules. These structures are responsible for the excretion of nitrogenous waste and help maintain osmoregulation by filtering hemolymph, the fluid equivalent to blood in these animals. The waste is then excreted as uric acid or other forms, depending on the species.
Light-independent reactions take place outside the thylakoids, in the stroma. The stroma is the fluid part of the chloroplast. The thylakoids are an abundance of saclike photosynthetic membranes.
