Cross-pollination relies on flowers to attract specific pollinators, facilitating genetic exchange and diversity among plant populations.

Asthma is characterized by chronic inflammation of the airways, leading to difficulty in breathing.

Bronchitis is characterized by inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

Bronchitis is the inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

Lung cancer is primarily caused by smoking, which introduces carcinogens that can lead to the development of cancerous cells in lung tissue.

The gametophyte stage is where gametes are produced in the plant life cycle.

The umbilical cord connects the fetus to the placenta, facilitating nutrient and waste exchange.

The ectoderm gives rise to the skin and nervous system during embryonic development.

The ovary of the flower develops into fruit after fertilization, enclosing the seeds.

Chloroplasts are the organelles that contain chlorophyll and are the site of photosynthesis.

The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery to other organelles.

The nucleus contains the cell's genetic material (DNA) and is responsible for storing and managing genetic information.

Mitochondria are responsible for synthesizing ATP through the process of cellular respiration.

The plasma membrane is selectively permeable, controlling the entry and exit of substances in and out of the cell.

Stomata are small openings on the leaf surface that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Flowers are the reproductive structures in angiosperms, facilitating pollination and seed production.

Stomata are small openings on leaves that facilitate gas exchange.

Xylem is the tissue responsible for the transport of water and minerals from the roots to the rest of the plant.

Roots are primarily responsible for the uptake of water and minerals from the soil.

The pistil, which includes the stigma, style, and ovary, is responsible for receiving pollen during pollination.

The sinoatrial (SA) node initiates the electrical impulse that triggers heart contractions.

The pancreas is responsible for producing insulin, a hormone that regulates blood sugar levels.

The lens is responsible for focusing light onto the retina, allowing for clear vision.

Alveoli are tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and blood.

The alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.

Endocrine glands are primarily responsible for the production and secretion of hormones in the human body.

The cell wall provides structural support and protection, maintaining the shape of plant cells.

The vacuole stores water and helps maintain turgor pressure, which is essential for plant structure and support.

The placenta facilitates the exchange of gases, nutrients, and waste between the mother and fetus.
